Anyone running these plugs? Magnuson recommends stock plugs and gap with their 6lb kit but my car will be making quite a bit more than a stock car with the kit, so I wanna go one step colder on the plugs. Don't wanna pay $160+ for iridium's when I can get coppers for half the price, I never keep spark plugs in long enough to make iridium's worth it anyway.
On a 5.7 eagle of course
