What is the recommended spark plug gap for Civic Exi -05 and How much it should be on CNG??
How it will effect Pick & Mileage??
What kind of plugs you got? If you got platinum plugs... they don't need to be gapped. If you do, you are going to mess up the plugs. As for the gap... check the owners manual or go to some store and ask them. Most stores carry plug gap guides.
Plugs do effect acceleration & mileage but you won't really feel the difference.. Unless the plugs are really old and dirty.

You gap the plugs according to the engine specifications. You can buy any brand and use it in your car as long as it's gapped properly. I have hever heard NGK or Bosh had their own gapping system...I have been working on cars for 2 years now and I always refer to the car manual... If not than the computer program that has all the info about the car repairs.
