Spark Plug Recommendation

[rogasm]

Next weekend I plan on replacing all coils and will also replace the plugs. Any recommendation on which spark plugs to use?

When my VCG's needed replacing about 4 years and 70k miles ago, I went with Bosch platinums.

Been firing fine every since.

Denso Iridium's. Not cheap but mpg has improved and they will pay off in the long run

I've always went with Bosch platinum plugs. Never had a problem

I'm sure you've heard but I meant to mention something regarding the +4's. Did a quick google search and this came up on a Subaru forum. Might be worth the read but I agree with them being a marketing gimmick and the spark traveling through the path of least resistance. Anyways, still going to say OEM.

Not very technical but a decent little read...

THanks for the recommendations.

I'm doing the same thing once I get the parts. I ordered 8 COP's(motorcraft DG515) and 8 spark plugs(motorcraft SP468) from autopartsexpress.com. I ordered them a few hours ago and it was 351.76 shipped. Also, I think LS's made before July 16, 2001 used spark plug #SP467. After that date, they switched to SP468.
