I own a 2018 Maruti Suzuki Ignis Delta petrol and am considering installing an aftermarket CNG kit. Is it a safe and worthy option? Also, what is the approximate cost of fitting an aftermarket CNG kit?
If the car is a 2018 Maruti Suzuki Ignis Delta petrol, fitting an aftermarket CNG kit can be a sensible decision if the monthly running is high enough to recover the installation cost. The Ignis' naturally aspirated petrol engine is generally compatible with a high-quality sequential CNG kit, and when installed by a reputed installer, it can be both safe and reliable. A good-quality sequential CNG kit with RTO endorsement typically costs around Rs. 50,000-60,000.
The bigger question is whether it is the right decision for you. CNG makes sense only if your running is high enough to recover the cost within a reasonable period. You will also lose almost the entire boot space to the cylinder, and there will be a slight drop in performance. If the car is driven only moderately, continuing with petrol may be the more practical option.
