simple plug question here

[clevelandfan]

hey, i got a 98 gp se with the 3.8. i was curious to what the best performing plugs were for this engine. i work for advance auto, so i will be gettin them from there :th_thumbsup-wink:

What kind of mods do you have, or is it stock?

 

[clevelandfan]

stock right now. plan on a high flow cat-back, and maybe wider front headers. and then of course a high flow intake. prob cold air. thats probably gonna be all for it. its 177k miles, so nothing too much. it will look pretty tho :th_thumbsup-wink:

 

[whiney]

I'd go with autolite 605's with .055" gap. And you should be good to go

 

[OH4CompG]

Agreed, Autolite 605's if you're an autolite fan. If you prefer NGK go with the TR55's

 

[clevelandfan]

cool. i think i lean slightly toward the ngks, but idk yet.

run the stock heat range. buy whatever plugs you want. its not going to make a difference on a stockish setup.
