Best spark plugs 95 YJ 2.5L?

Hey guys I have a question about the correct spark plug reach for the 95 YJ 2.5L, I see that some are .460 reach and others are .750, want to make sure I order the right ones to do a tune up. The plugs in their now are NGK V-power R5 plugs.

Copper, copper, copper. Did I mention to use copper? Plain old Champion Coppers are perfect.

Now that you have copper spark plugs, set them to the factory spec of .035 and you'll be back on the road without a problem.

I'm using NGK (7252) FR5-1 V-Power, but Champions would be my 2nd choice

Rich, it's a pretty simple search when using an auto parts store's website.

Here is what I found for Napa: http://www.napaonline.com/napa/en/p/...443_0065775497

Depends on how cheap. I had cheap wires and it looked like a light show in my engine compartment with arching, I went with MSD wires and could feel the smoothness at idle and crisper acceleration. I'm not saying you have to spend $90, but I sure wouldn't buy the cheapest.

As long as they are OEM spec, then you've got nothing to worry about!
