I called a shop to ask what type of plugs should i replace the stock plugs with.

Here is what they told me:
replace old with NGK BPR 7ES

I pulled the stock plug and:
it is a NGK IGR7A-G

Is the bpr 7es a good replacement or should I stick with the IGR7A-G??

Please help!!!

yes, good choice... great plug cheaper price... gap them at .26 and change them around every 10,000 miles... i change every oil change.. small ins..

also the next time get bpr7s, even better plug..

Farmer, BPR7ES/8ES is the proper nomenclature.

Also, being tuned doesn't mean he should use 8s. You _only_ use a colder range if you're blowing out the hotter range. It's better to stick with 7s as long as possible.

Rio-evo, a quick search would have shown you that the BPR7ES is copper and is the preferred plug on the Evo. Next time, do a little research before freaking out.

For turbo cars IMO, Copper > Iridium > Platinum = a big no for turbo cars. Something to do with Platinum not with standing the heat and pressure from turbo cars.

Indeed, the twinturbo ZR1 project I completed would not let us use the platinum plugs as the car would run like crap under boost. Changed to some new platinum plugs and it still ran like crap. We finally changed to a standard plug and the problems were fixed. This was at the suggestion of Lingenfelter.

I think the E is for extened tip. Is that really necessary?

Warrtalon

P is for protruding tip. I've never heard of nor seen an NGK BPR7/8 without the E, but that's what Farmer says he uses. I've never heard of anyone using one without the E.

Same here.

I use the br8es and I like it better.
