Introduction to CNG Kits
CNG (Compressed Natural Gas) has become one of the most popular alternative fuel options for car owners in India, thanks to its cost-effectiveness, eco-friendliness, and excellent ROI.
At Mittal Car Care, we do not provide any after-market CNG fitting services. We only work with company-fitted CNG systems, offering expert CNG scanning, maintenance, and repairs using advanced diagnostic tools and genuine spare parts.
But as service experts, we believe in sharing honest advice so you can make the right decision if you’re planning to go for CNG — whether company-fitted or after-market.
Who Should Opt for a CNG Option?
✅ Daily commuters with high monthly mileage
✅ Taxi & fleet operators looking for better ROI
✅ Environment-conscious drivers aiming for lower emissions
✅ People planning to keep their car for at least 4–5 years
Company-Fitted CNG vs After-Market CNG
Feature | Company-Fitted CNG | After-Market CNG |
Warranty | Covered by manufacturer | Voids manufacturer warranty |
Safety | Pre-tested & factory-approved | Dependent on installer’s skills |
Resale Value | Higher | Lower |
Service | At authorized centers | At CNG fitter’s shop |
Compatibility | Engine tuned for CNG | May require adjustments |
Fit & Finish | Factory neatness, clean usage feel | Varies based on installation |
Why Company-Fitted CNG Feels Premium
One major plus of company-fitted CNG is the perfect integration:
No major modifications after purchase.
Pipelines, wiring, and fittings are factory neat.
Clean usage feel — switches, indicators, and fuel modes work seamlessly.
Minimal risk of poor installation or mismatch.
If you want peace of mind and a premium feel, company-fitted is the way to go.

Great ROI – huge fuel savings in the long run.
Faster filling – after-market CNG can sometimes fill quicker than company fitted due to different nozzle design.
