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.

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 # R5671A-10 for the 125 shot.

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.

Why are you running them when you haven't sprayed yet..... Has the bottle even been filled yet ?

OOPPS
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.

Noobie Q.

Does it really make a difference which plug in a stock LT5? I use the ac delco replacement for the FR2LS plugs that came in my 90.

TIA
