Changing Civic Spark Plugs
Q. Hi Mr. Ciulla, I just bought a set of new NGK spark plugs for my Civic. In the car's manual, it says the gap should be 1.1mm or .04". My question is, which number do I use. Those two numbers do not line up on the spark plug gapper, and therefore I have two choices?
Oh, and how do you install them if you do not have a torque wrench? Can I just turn them until I feel them catch, and then turn them 2/3 more?

AlysiaA. Either number is good. As you can see the actual spec is 0.043" which is right in the ballpark.
Engine Type Spark Plug
(NGK)Gap D16Y5 ZFR4F-11 1.1 MM / 0.043" D16Y7
D16Y8ZFR5F-11 1.1 MM / 0.043" B16A2 PFR6L-13 1.3 MM / 0.051" Apply a small quantity of anti-seize compound to the plug threads, and screw the plugs into the cylinder head finger-tight. Then torque them to 13 foot pounds which is about a ¼ to ½ turn.
