I was wondering what the best plug is to run in the 5.0's. I just got the car (an 88 GT) and I'm giving it a tune up. It has Autolites in it that are real nasty and I got some Bosch Platinum plugs and have heard good and bad about them. What do you guys use? Also, these platinums are shorter than the Autolites. Is it just the design or is it not right? Thanks.

Well, for Saturns, they GENERALLY run like crud with the Platinums in there.



We stick to NGK. They're cheap and work great.

 

Ive had good luck with accel and motorcraft

 

Regular stock Motorcraft plugs. That's all I put in my car (or Autolites, same thing)

 

i have NGK's man do i feel the power increase over those old motorcrafts.... lol only beacasue i did 9 mm wires along with the plugs lol...

 

Alright, yea, I'll be putting a set of 9mm Ford Motorsport wires on it at the same time. So basically NGK or Motorcraft/Autolite?

 

You did not feel a difference with plugs and wires.

 

I dunno, I've seen dyno's of gains messing with sparks on small blocks. Granted they were distrubuters and carbed (I've got DIS and injection, so no real gains for me).



In my world of the 1.9L LLO (Saturn 1.9L engine), wether you got a DOHC or SOHC, all you'll really get is a smoother idle.



This may change in bigger engines trying to ignite more stuff. Make it easier to run the spark, that's more juice to the combustion chamber, which is a hotter spark.

 

What should I set the gap at?

 

I don;t know either Lloyd, maybe it's in my head, but the car seems so much more snappier with new plugs and wires. Maybe that goes along with the same mentality that gears add hp. <img border="0" src= smileys/smiley4.gif>
