What kind of spark plugs do you all recommend for the 4.0 WJ. I have added a lot of weight to my jeep and would like to pick up as much power as possible. I'm sure it won't be a lot from just spark plugs but I run splitfire plugs in my camaro and it seems to pep it up a bit... just looking for the same kind of response on my jeep!
Right now, i'm thinking about getting Bosch Platinum 2's
Any other recommendations ?
Thanks
Chris
