CNG Kit Installation in Kia - Sonet, Seltos, Carens, Syros

Certified sequential CNG kit installation in Kia passenger vehicles across India.

CNG Kit Installation in Kia

Kia has rapidly become one of India's most loved car brands, known for striking design, premium features, and top-tier safety. From the stylish Sonet and the feature-packed Seltos to the family-focused Carens and the newly launched boxy Syros, Kia cars are everywhere.

However, Kia vehicles are slightly heavier and their engines are tuned for performance, meaning petrol running costs can be higher than rivals. Aftermarket CNG kit installation in Kia offers the perfect solution. Unlike factory CNG, aftermarket installation allows you to choose premium Italian kits, larger 60L cylinders, and precise ECU tuning—especially crucial for Kia's Smartstream engines.

Whether you want to convert your Sonet for daily commuting or your Carens for commercial use, our CNG kit installation in Kia service ensures factory-like refinement, safety, and complete RTO endorsement.

4. Why Choose CNG Kit Installation in Kia?

Kia cars offer excellent build quality and premium features, but their petrol engines are tuned for performance, which means real-world fuel efficiency often hovers around 10–14 km/l in city traffic. With petrol prices remaining high, running a Kia can be expensive. After CNG kit installation in Kia, your running cost drops dramatically to ₹2.50–₹3.50 per km.

For a ride-hailing driver using a Carens or Seltos, CNG kit installation in Kia is highly profitable. For a family using a Sonet or Syros for daily commutes, the payback period is just 8–12 months. Kia's suspension is tuned on the firmer side, which actually helps handle the added weight of a CNG cylinder better than softer setups.

5. Aftermarket CNG vs. No Factory CNG

Unlike Maruti Suzuki or Hyundai (which offers some factory CNG options), Kia does not offer any factory CNG variants in India. Therefore, aftermarket CNG kit installation in Kia is your only option if you want to run your car on gas.

The advantage here is complete flexibility:

  • Any Variant: You can install CNG on top-end variants (HTX+, GTX+) which usually don't get factory CNG from other brands.
  • Choose Your Kit: You can select premium Italian kits (Lovato, BRC, Tomasetto) instead of standard OEM kits.
  • Cylinder Size: You can choose a 55L or 60L cylinder based on your boot space needs.
⚠️ Engine Warning: Kia's "GDi" and "T-GDi" engines (Turbocharged Gasoline Direct Injection) require specialized CNG kits with GDi emulation. Standard kits will cause severe running issues. Diesel variants are not eligible for CNG conversion.

6. Understanding Kia Engines & CNG Compatibility

Kia uses several engine families. The CNG kit installation in Kia process depends on the engine:

  • 1.2L Smartstream MPi (Sonet): A 4-cylinder engine with multi-point injection. Very easy to convert. Standard sequential MPI kit is perfect.
  • 1.5L Smartstream MPi (Seltos, Carens): Larger 4-cylinder engine with multi-point injection. Requires a high-flow reducer but is highly compatible with CNG.
  • 1.0L T-GDi (Sonet, Syros): Turbocharged Direct Injection. Requires a specialized turbo-capable sequential kit with GDi emulation modules. Not all installers have this expertise.
  • 1.5L T-GDi (Seltos, Carens): Turbocharged Direct Injection. Highest performance engine. Needs a heavy-duty GDi-specific kit. Installation is advanced and requires expert tuning.

8. CNG Kit Installation in Kia Seltos

★★★★☆ 4 / 5 — Best with 1.5 MPi Advanced Install

The Seltos is a premium SUV with a large road presence. CNG kit installation in Kia Seltos is highly recommended for the 1.5L MPi engine. The 1.5L Turbo GDi is a performance beast, and converting it to CNG requires the absolute best kits and tuning to avoid injector issues.

Engine Options
1.5L MPi / 1.5L T-GDi
Power / Torque
115 PS / 144 Nm (MPi)
Transmission
6MT / CVT / 7DCT
Boot Space (Petrol)

Engine & Kit Recommendation for Seltos

For the 1.5L MPi, a high-flow sequential MPI kit from Lovato or BRC is perfect. For the Turbo, do not compromise—use a premium GDi-emulation kit and ensure the installer has proven experience with direct injection engines.

Performance & Mileage

  • CNG Mileage: 18–22 km/kg (MPi, city), 16–20 km/kg (Turbo).
  • Range: 300–380 km on a 60L cylinder.

Boot Space

Boot Space Retained (60L cylinder)~58%

Pros
  • Huge boot space even after conversion
  • 1.5L MPi is reliable and torquey on gas
  • Premium feel maintained
Cons
  • Turbo GDi conversion is very expensive
  • Heavy car means slight power drop on 1.5 MPi

Indicative Cost: ₹42,000 – ₹58,000 for CNG kit installation in Kia Seltos.


MPV CNG Kit Installation in Kia Carens

9. CNG Kit Installation in Kia Carens

★★★★☆ 4.5 / 5 — Ultimate Family CNG Moderate Install

The Carens is a spacious 6/7-seater MPV. CNG kit installation in Kia Carens transforms it into an incredibly cheap family hauler. The 1.5L MPi engine is the best candidate; it has enough torque to handle a full load and a CNG cylinder.

Engine Options
1.5L MPi / 1.5L T-GDi
Power / Torque
115 PS / 144 Nm (MPi)
Transmission
6MT / 6iMT / 7DCT
Boot Space (Petrol)
216L (3rd row up)

Engine & Kit Recommendation for Carens

A robust sequential kit with a high-flow reducer is necessary. For the Turbo, again, GDi emulation is required. The installation must be done carefully to ensure the 3rd row remains usable if a smaller cylinder is chosen.

Performance & Mileage

  • CNG Mileage: 18–22 km/kg (MPi, city), 16–19 km/kg (Turbo).
  • Range: 300–360 km depending on load.

Boot Space

Boot Space Retained (60L cylinder)~40%

With the 3rd row up, boot space is only 216L. A 60L cylinder will take up most of it. Most commercial users fold the 3rd row for maximum luggage + CNG space.

Pros
  • Massive fuel savings for a 6/7-seater
  • Strong 1.5L engine for family loads
  • High resale value
Cons
  • Compromises 3rd-row luggage space
  • Turbo DCT tuning is critical

Indicative Cost: ₹45,000 – ₹60,000 for CNG kit installation in Kia Carens.


Compact SUV CNG Kit Installation in Kia Syros

10. CNG Kit Installation in Kia Syros

★★★★☆ 4 / 5 — New & Promising Advanced Install

The Syros is Kia's newest boxy compact SUV, featuring the punchy 1.0L Turbo GDi engine. CNG kit installation in Kia Syros is a great way to reduce running costs on this stylish daily driver. The boxy design means excellent headroom and a flat boot floor, making it easy to fit a large cylinder.

Engine Options
1.0L T-GDi / 1.5L Diesel
Power / Torque
120 PS / 172 Nm
Transmission
6MT / 7DCT
Boot Space (Petrol)
~390 Litres (Est.)

Engine & Kit Recommendation for Syros

Since the Syros only comes with a Turbo Petrol (and Diesel), you must use a GDi-emulation sequential kit. The turbocharger demands a high-flow reducer to maintain performance.

Performance & Mileage

  • CNG Mileage: 20–24 km/kg (city), 25–28 km/kg (highway).
  • Range: 320–380 km on a 60L cylinder.

Boot Space

Boot Space Retained (60L cylinder)~55%

The tall boy design of the Syros means the cylinder fits neatly without intruding into passenger space.

Pros
  • Turbo engine retains great performance on CNG
  • Boxy shape accommodates cylinder easily
Cons
  • Only Turbo Petrol available (higher conversion cost)
  • DCT gearbox tuning is critical

Indicative Cost: ₹42,000 – ₹50,000 for CNG kit installation in Kia Syros.


11. Which Kia Model Is Best for CNG Kit Installation in Kia?

Best for City Commuting

Sonet (1.2 MPi) or Syros. The compact dimensions and efficient engines make these the cheapest to run and easiest to park. Perfect for daily office runs.

Best for Highway + City Mix

Seltos (1.5 MPi). Offers the best balance of performance, premium comfort, and reasonable boot space retention after CNG installation.

Best for Boot Space

Seltos. With a massive 433L boot, you still have over 250L of luggage space even with a 60L cylinder installed.

Best for Families

Carens. The 7-seater configuration is perfect for large families, and CNG drastically reduces the cost of long family trips.

Lowest Conversion Cost

Sonet (1.2 MPi). The naturally aspirated engine requires the simplest sequential kit, making it ideal for budget-conscious buyers.

Best for Performance on CNG

Seltos / Carens (1.5 Turbo) or Sonet (1.0 Turbo). With a GDi-specific kit, these engines retain their punchy performance even on gas.

12. Sequential vs. Venturi: The Only Choice for CNG Kit Installation in Kia

Every modern Kia car (BS6) uses electronic fuel injection. A Venturi (conventional) kit is completely unsuitable for CNG kit installation in Kia. It will cause:

  • Severe power loss.
  • Backfiring and potential damage to the intake manifold.
  • Check Engine Light (CEL) errors.
  • Rejection at the RTO (no AIS-024 certification).

A Sequential MPI kit uses the car's original ECU signals to fire CNG injectors in sequence. For Kia's GDi engines, the kit must also include a GDi emulation module to prevent the petrol injectors from misfiring or throwing codes while running on gas.

13. CNG Kit Installation in Kia Price & Timeline

Model Group Engine Type Recommended Kit Type Indicative Kit Price Installation Time
Sonet (1.2 MPi) / Carens (1.5 MPi) / Seltos (1.5 MPi)MPi (Multi-Point Injection)Sequential MPI₹36,000 – ₹52,0005–6 hours
Syros (1.0 Turbo) / Sonet (1.0 Turbo)T-GDi (Turbo Direct Injection)GDi Emulation Sequential₹42,000 – ₹50,0007–8 hours
Seltos (1.5 Turbo) / Carens (1.5 Turbo)T-GDi (Turbo Direct Injection)Heavy Duty GDi Sequential₹48,000 – ₹60,0008–10 hours

Note: Prices are indicative for CNG kit installation in Kia and include kit, installation, and basic RTO paperwork assistance. Final quote depends on your city, cylinder size (55L/60L standard), and kit brand.

14. RTO Endorsement & Legal Requirements for CNG Kit Installation in Kia

Driving a Kia after CNG kit installation in Kia without an updated Registration Certificate is illegal. The RTO must endorse the fuel type change on your RC. We handle the entire RTO process for your CNG kit installation in Kia. You will need to provide:

  • Original RC.
  • Valid insurance (with CNG kit declared).
  • Valid PUC certificate.
  • AIS-024/AIS-028 type-approval certificate (provided by us).
  • Installation certificate (provided by us).
  • PESO hydro-test certificate for the cylinder (provided by us).

Endorsement typically takes 7–30 working days depending on your RTO district.

15. ECU Tuning for CNG Kit Installation in Kia Engines

Kia's Smartstream engines are highly sensitive to air-fuel ratio errors, especially the GDi engines. A "plug-and-play" CNG kit without proper laptop tuning during CNG kit installation in Kia will cause lean/rich running and check engine lights. Our technicians connect a laptop to the CNG ECU and the car's OBD-II port after every installation. We monitor fuel trims and adjust the injection map for smooth power delivery and cold-start reliability.

16. Maintenance & AMC After CNG Kit Installation in Kia

  • Every 5,000 km: Visual inspection of high-pressure lines, leak test, and ECU diagnostics.
  • Every 20,000 km: Replace low-pressure gas filter.
  • Every 3 years: Cylinder hydro-test (mandatory by PESO).
  • Spark plugs: Inspect every 15,000 km. For Turbo GDi engines, use only OEM-specified iridium plugs.

17. Warranty & Insurance Impact of CNG Kit Installation in Kia

Warranty: Aftermarket CNG kit installation in Kia typically voids the engine and powertrain warranty (Kia offers 3 years/unlimited km standard). The rest of the vehicle's warranty remains intact.

Insurance: You must inform your insurer immediately after CNG kit installation in Kia. The policy needs to be endorsed to include the CNG kit. The premium increase is usually ₹1,500–₹3,500.

18. CNG Kit Installation in Kia Process Step-by-Step

  • Health Check (1 hour): Scan OBD-II for existing faults; check engine compression and spark plugs.
  • Mechanical Fitment (3–4 hours): Mount cylinder brackets to chassis; route high-pressure line; install filling valve.
  • Plumbing & Wiring (1–2 hours): Install reducer, connect coolant lines, wire CNG ECU and injectors.
  • Leak Test (30 mins): Pressurize system and apply soap solution to every joint.
  • ECU Tuning & Road Test (1.5 hours): Calibrate fuel trims on laptop; test drive on petrol and CNG.
  • Documentation Handover: Provide installation certificate, PESO certificate, and guide you on RTO submission.

19. Frequently Asked Questions About CNG Kit Installation in Kia
