Both Denso and NGK are good brands, anything above than that will be overkill for CNG vehicle.

Denso is quite good for CNG fitted vehicles, i used the same in Wagon-R ReCNG performance was good, avoid champion from Maruti MGA they are good for Petrol cars only


Mediocre me
What is recommended for SX4 CNG? Denso/NGK?

I remember the stock were costing Rs 65 per plus.
