Ok I went on the NGK site to scope this out, this might be a stupid question so flame on lol but is the a huge difference in the LASER IRIDIUMŽ and the Iridium IX? I didnt see that they carried the IX anymore for my car.

I really don't think so, from what i understand about iridium its a good conductor and the good thing about it is that i lasts longer than copper. The latest issue of D-Sport has an article on the electircal conductor spark plug that supposedly added 4whp to an evo 9. They even have the dyno sheets to back it up.

 

Yeah Im thinking though it is diferent in price. I was reading up on them on an Evo site and they said the BRP7EIX are for lightly modded evos. the 6's are for stock and the 8's are for big turbo's and heavy modded.

Im about to instal NGK -R copper plugs I bought the BPR7Es . I have used them on my previous car(All motor LSVTEC Integra 12.1 compression) and I found out that they did the job. Good price too.

 

if you have mods go with BPR8ES. I think the part number is 3923

 

ok thanks
