hi guys i have a quick question i have a vortec g35 and a wile back i was asking serviceing questions and some of u recomended that i get plugs 1 degrese cooler.
so i bought some and im going to put thim, in they are ngk heat leval 6.
but i was wondering if i need to gap these?
thanks alot guys.

 

they should be pregapped

 

They should but all are not. Check them. I did mine today all where on the small side (-.002 gap). Have a look at them just to be sure.

 

Just check them all to see if they need it or not.!!

 

depends on what you buy...i bought denso iridiums and they are pregapped and will be damaged if you try to

 

They should be correct but the oem gap is 0.044 if you need to know. I always check to be safe.

 

ok thanks guys
