you dont get any horsepower with a spark plug...stick with a reputable, good quality brand,such as denso,ngk or ac...ive had bad experience in the past with splitfire plugs,and i do not recommend them.

Come to think of it...I would blame the splitfire plugs for messing up my Mercruiser engine in my boat! They'll be in the trash soon!

NGK Iridium TR55IX...that's what I am running...recommended by Corey Henderson.

I agree with ully . just one note if you ngap them (45th for me) be very carefull as you dont want to damage that skinny little tip I use a gap ring and slide it till it just barely touches. and allways anti sieze

I believe if you talk about a specific plug, they are different for the '90-92 motors and the '93-95's. I'm pretty sure NGK has different plug types listed for each, though you can get them in the same heatrange and iridium for both, just a different number. I can't recall what the difference was, though, I wanna say one has a washer and one doesn't? Or one has a tapered seat and one doesn't? I can't recall...

On the antisieze, I've never done that to any car. Guess I better get some and pull the plugs out and apply it.

That's it, the ones for my `94 are tapered and the 90-92's are flat.
