precautions while using cng

To prevent any misfirings that tend to result from insufficient spark generated by the spark plugs, it is very important that the spark plugs are checked on a regular basis and replaced with new ones after every 13,000 15,000 kms.Also, the performance of a CNG car can be greatly improved if instead of continuing to use spark plugs meant for a petrol car, users opt for spark plugs specially designed for a CNG vehicle.
