Spark Plug Inquiry

Post by PearlBeauty » Wed Nov 02, 2005 6:09 pm

Gonna be doin plugs on my car here within the week, was wonderin if OE plugs or aftermarket are the way to go. If OE does anyone have a part #, and if aftermarket, what would you recommend... Also since i'm runnin 14lbs of boost i was told that i should gap the plugs down a bit (as it hesitates at higher boost). Anyone know exactly what gap i should run, and or how much to differ from stock.

See the chart on this page:

Basiclly the PFR6J-11 are the stock platinum plugs. For your car I'd say just get these and gap them down to .034.

If you were running on the edge all the time at 17psi, I'd say get copper plugs one range colder, like BCPR7ES or BKR7ES-11.

Make sure to buy NGK plugs and not some other brand. Our engines don't seem to like other brands.
