What is the difference between those and the ES model plugs?

I kinda thought that, but I figured I'd make myself look like a *** instead.

BUMP....

I have another question for some of you guys. I went ahead and put some new BPR7ES's in my car today. I gapped them to 26 like a few of you are doing. When I took my old plugs out, I checked the gap on them out of curiosity and they were at like 36. The plugs looked fine, but after putting my new ones in my car felt like it was running better and seemed to have a little more power on the butt dyno. Could them being agpped like that make that much of a difference or is it a mental thing? What could the plugs being gapped like that do to my car?

 

DENSO IW22's I have them and they come right out of the box pre-gapped. FIXED my Po300 problem right off the bat! This is stock heat range and you have to be careful not to get the IW23's witch will O*W#$ u UP. hope this helps.

 

Yes the gap will make a huge difference, and it was probably the reason you were getting a CEL. If you talk with Al even he will tell you to run the stock plugs. You could go with the BPR8ES for a colder spark. However, the plugs may burn out (so to speak) quicker.

Stick with the BPR7ES gapped at .26 and you should be cool.

See you this weekend.
