Typically with cars and trucks it is the gap in the spark plug that is being talked about. Most cars have a sticker in the engine compartment that has your vehicles gap. Typically you have to hold the spark plug up and insert a feeler gauge to get the right gap. When you do have the right gap, the car/truck tends to run smoother.

Anywhere between. 038 to. 042 would be the right gap settings.

the spark plugs must be change at 30 000 k/m if you use gasoline (octan 95) the gaps are already fix distan. 1.5mm . for new spark plugs , it will come up by use and consumptions , check the distan. for the metal on the meddle par must be 2.5 mm for new spark plugs by consumption it will go down to the meddle white cover.

They should be pre-gapped when you buy them. The gap is .031 to .035. Open a package of plugs and you will see that they are not "pre-gapped" but vary widely in a set.

if this is a four cylinder engine,the plug gap is what NAPA told you,verify you have the right plugs and gap,next remove the cap again and verify the plug wires are pulled into cap where they will lock in.

Read the labels under the hood. Spark plug gap can quite often be found on one of the labels somewhere in the engine compartment.

If not, then the owners manual or a service manual that you can purchase.
