Do i need to gap these are just throw them in. If I need to gap what gap should I use.

 

no need to gap them.

 

i was under the impression that u should always check the pre-gap plugs juss to ensure that they are within spec.
i'd check them juss to make sure.

 

I wouldn't on iridium plugs. The electrode is too small and fragile to stick a feeler gauge in there. Plus it says right on the box not to adjust gap because you may inadvertently damage the electrode, or at least mine did.

I remember reading somewhere not to gap platininum plugs wanted to make sure that I didn't have to do the same with these. Hope these work a lil better than my stock plugs with my 70 shot.
