Re: which plugs are you guys using (uneekcrx)
With Forced Induction (FI) most people run "NGK BKR7E" plugs gapped at like .030-.032 for factory ignition, and like .040-.042 for aftermarket ignitions. I hope this helps.

Are they gapped the size you recommended for stock out of the box, or do you have to do that yourself?

A bigger gap gives a "bigger" spark and with an aftermarket (high output) coil and/or ignition box it will be able to produce "more" spark than stock to "handle" the larger gap...
Sorry, best way I could think of to explain it

So do you need to do the gapping?? With a stock ignition the the plugs you suggested work without being gapped?

dude... you should always double check the gapping on the spark plugs. dont always think that it is properly gapped right automatically. better to be safe than sorry. you can recheck the gap in under a minute with all the plugs out of the box. its that simple.
what MPLEX said is pretty much what it is. the bigger the gap... you more spark youll need. on a colder plug, youll need to gap it less for the stock ignition to provide a good spark. aftermarket units like MSD offer stronger sparks than stock ignition, so it can efficiently provide a good spark for larger gaps.

Re: which plugs are you guys using (SlowB16)
I've been using NGK BCPR7ES-11s for my turbo D16Y8, except recently, I switched to NGK BCPR6ES-11s... just wanna see how different they are really. I figured I'm running <7psi anyway, and the 7s started going bad after only 6000 miles (and I drive VERY hard...), so perhaps the 6s will last longer... Gap's about 0.030" - 0.032" or so w/ my Honda ignition.

I use densi iridiums on the street, two stages colder than stock, I use beru racing plugs at the track, they are remanned champs or boasch that have a 360degree electrode. They foul real easy though, so only for track use.
