Iridium plugs are by far the best. Go with NGK iridiums for imports. Denso iridiums if they're out.

1. Why does this post have a title that says absolutely nothing about the topic?

2. Iridiums are not the best, you only think that because you saw it is some ad.

3. Standard NGK plugs are your best bet. I don't know what size the 420A takes, so you will have to find out.

The "best" for cost and performance will be NGK BPR6ES plugs, same as a turbo but gapped to .040".

An iridium plug will last longer, but not do much different so far as running is concerned. The DSM ignition system will run just about any plug in the non-turbo, but the design -for reasons I'm not sure can be explained, but seem empirically true- seems most pleased with the NGK line.

Copper plugs are by far the best. Not sure if there is a difference between the bpr's and the bkr's, but i guess it could be the difference between 4g63 and 420a.

The 2gnt guys (like me) use:

ngk bkr5e-11 copper are one range hotter then stock.. I use them but haven't really noticed any difference.

ngk bkr6e-11 is stock range.

Gap either 0.045-0.053

I'd stick with the BPR6ES, some will prefer the 7s. If you're mostly going to be driving like the rest of us wage slaves, and not spending every damned night at the track, stay with the 6s.

I have the stage one kit as well and the first thing I would do is to go to an autoparts store and get another breather because the one that comes with the kit will melt.

Hey people. As of right now, I am running Champion platnum plugs (I know, I know!) I think I am going to get rid of them. I was just wondering what the best type of plugs were out there, what do you guys have, give me some recommendations please! Thanks.

PS. I have MSD 8.5mm wires on right now. Ive noticed the Champion plugs to be fouling in certain scenarios, such as passing people up hills, and sometimes during town driving.

I hate people that just say SEARCH........but SEARCH and don't tell me typing in "spark plugs" doesn't give you 30 of these topics.


Best and Only spark plugs to use:

NGK BPR7ES or if boosting over 17psi BPR6ES
