It's time for a tune-up. Since my jeep is a 2000 i only need plugs (for the ignition). My question to you....

What plugs do you use and what gap do you set them at?

Never changed the plugs. Figured it was time.

 

Champion copper standard plugs(OEM) set at .035

 

I like autolite part #985 in my 4.0L

 

You will also need 6 spark plug boots napa belden 702421

 

I always use Champion plugs gapped at .035" in my ZJ's 5.2L V8.
