Hi Team, I have a 2021 Kia Seltos HTK iMT and am planning to install an aftermarket CNG kit due to my increased running. Could you please confirm whether the iMT gearbox works well with an aftermarket CNG setup? The car has currently run 8,000 km.
We would strongly advise against installing an aftermarket CNG kit on your Kia Seltos HTK iMT. This Kia car uses a direct injection turbocharged petrol engine, which isn't well suited to aftermarket CNG conversions. The iMT gearbox adds another layer of complexity, as the system relies on precise engine and clutch control, and CNG conversions could affect drivability and calibration. More importantly, Kia does not offer a factory CNG option on the Seltos, so any conversion would void your warranty and introduce reliability risks.
If your running has increased significantly, it would be more sensible to replace your Seltos with a diesel car or consider a factory CNG model where the engine and fuel system are designed to work together from the factory.

@autocar.india my car doesn't have turbo, it is naturally aspirated engine with IMT gearbox.
