what spark plugs are you guys using?

are the NGK BKR5EIX the plugs of choice on a stock engine?

Yep, I run the iridium plugs on my car and customer cars. Plug # 6341 for your car.

Jeff's 100%. 90-92's NGK stock no: 6341=BKR5EIX. on 93-95 NGK stock no: 7164=TR55IX. these would be more for stock or close to stock applications. on 90-92's in a pinch you could use NGK FR5's too.

i went to parts store and ngk.com said to use plug #5464 BKR5EIX-11 not #6341 for my 90. what ones should i use?

I settled on the NGK BKR6, a step colder than the stock plug. The BKR7s were a bit too cold. They're gapped at .040". Looking at the ground strap and after some plug cuts, the 6s were just about right. BTW, I'm with bldavis on using regular NGKs.

I believe I'm using the BKR7EIX. Keep in mind the '90-92 plugs have a different seat than the '93-95 plugs when comparing part numbers.

NGK #FR5's for the 125 shot and 10's for the 150 pill.
Just what others are running.
From the NGK web the 10's are only 2 sets colder. Plug are not fouled, must be ok to run. I dont need a hot plug for smog.
