guys,

These the right plugs? Autozone tried to tell me we had copper plugs, even showed me their system stating copper plugs. I thought platnum and I looked up the spark plug code and amazon is selling these.

Will I have to gap them?
Any tips to replacing them?

What's the best tool?

yeah that looks like them, I'd recommend NGK BKR7EVIX-11 Iridiums as an upgrade part, but whatever you prefer. The plats should come pre-gapped, the Iridiums I list usually require gapping. There is a DIY for spark plug replacement, a torque wrench that will measure 18 ft lbs is a good idea. I always use a touch of anti-sieze on the plug threads and a dab of dielectric grease on the inside of the coilpack boots.

just so you wont get confused..

 

Saw this. It wasn't very helpful on avoiding cross threading... note the user starts off with a power tool.

How do I ensure I don't strip my head?

 

Thanks. I notice they are the same price on Amazon

 

you put the plug in the socket with a long extension and thread the plugs in by hand in for each cylinder until they seat, then use the torque wrench to finish the tightening and crush the gasket. Install and remove plugs on a cold engine, rather then a hot engine (I've done it on hot engines a hundred times without issue but the right way to do it to be safe is on a cold engine). Use some anti-sieze on the plug threads. Follow these rec's and you'll never worry about wrecking threads. Torque wrench is key, no power tools anywhere near the head.

 

^use very little anti seize, if you use a lot it WILL melt and drink into the cylinder. but yeah, if you thread it by hand it is impossible to crossthread if you know anything about machinery. if its not going down smoothly, its not sitting properly. I like to spin the plug 1/2 turn backwards before screwing forward...seems to help "line up" the plug before it goes in. (dont knock it til you try it )

 

I do they same thing with everything. I like to feel the threads "click," that is, where the threads start and stop just pass each other. You can feel them rise and then drop and you know you are good to tighten.
