I just bought my '03 Evo VIII last week and I wanted to change the plugs in it bc I didnt know what was in there. I bought NGK R BPR8ES and I took out NGK Iridium's. The Iridium's are still in pretty good condition and the car has only 33k miles. So should I put the Iridiums back in it? Or keep the BPR8ES? I gapped them to .030 just so you know.

Thanks

 

what mods on the car? I would suggest bpr7es if your not heavly modded 0.24-0.26 gap

 

I run BPR7ES (copper) with gap .020-.022

I have to change them often but they are cheap, efficient and easy to put in

 

Mods are 3in TBE, AEM intake, AEM filter and a MBC

 

ya stick with bpr7es cant go wrong

 

Sounds good thanks alot!

 

Put the iridiums back in if they look to be in nice shape, they're generally good for 60k miles. The IX's came with iridiums from the factory and I pulled mine out at 43k miles and they still looked and functioned perfectly.

 

Yea I was gonna throw those back in there bc there suppose to be a better plug. And didn't the VIII's come with Iridiums also?

 

Pretty sure the NGK BPR7ES was the VIII OEM plug, but yes, iridiums are better for multiple reasons including a much longer life.

 

Ok thanks I appreciate it
