Factory Fitted CNG kits
Manufacturers such as Hyundai and Maruti Suzuki provide a few of their models with factory-fitted CNG kits. Maruti offers plenty of cars such as S-Presso, Alto, Wagon R, Ertiga, and Celerio with pre-installed kits. Considering that these automobiles are produced using company manufactured kits, the performance of these cars remains constant and seamless.
The suspension, engine tuning, and the rest of the mechanical modifications are already done until the vehicle is rolled from the manufacturing line. You can distinguish between an aftermarket kit along a factory kit. Normally, in case of the latter, the CNG is filled from where the petrol is filled. Nonetheless, in the aftermarket one, you need to fill it by opening the bonnet.
One drawback is the fact that it includes a relatively smaller cylinder and so supplies a reduced driving range. The costs of the kits are almost the same, so that is one point where the two of them possess a tie. One must certainly opt for company fitted kits while considering a new car.

Maruti Suzuki, which is one of the most reliable factory fitted CNG car brand calls its CNG-powered vehicles S-CNG or Smart-CNG and asserts that their new CNG kits allow vehicles to run smoother.
On the flip side, if you decide on a Sequential CNG kit from an aftermarket vendor, all you must have is a car that accompanies an Electronically Controlled Injection system. The S-CNG and Sequential CNG kit will conduct the same and provide the vehicle a decent performance, provided they are both from precisely the same brand which is hard to get. Regrettably, installing an aftermarket CNG kit from your car will immediately void the warranty from the manufacturer.
