4 trailing plugs ??
When i got my used engine wich i had to take out of the wrecked car myself. There were 4 trailing spark plugs in it. Is there a reason for this or did someone just screw up?

You run 9's all around because they last longer in the leading position. Also, if you're lightly modded, then you want a cooler plug because of detonation. That and you can't get them mixed up!

the leadings will last longer. the above was wrong. the leadings will give a bit more low end power I think. if you're stock, just leave the stock plugs. modded turbos can run all trailings for a bit of safty. maybe a bit of top end gain.

I run 4 trailing plugs, but I have a T2 that runs 10 psi of boost.
This is not a mod for NA's... and hardly a mod at all. Not worth the money to change it until you're due for your next plug change.

i had the local advanced auto buy 8 trailing ngk plugs for the rx7. 4 platinum, 4 copper Which ones should i buy? as i was told 4 trailings could be beneficial to me as i am running 10+ psi boost on a modified TII.
Thanks
