I'm planning on going on a 900 mile road trip here in a few weeks and I was wondering if maybe I should put in the 103s before I go? Basically, I just have a CAI and FSWerks exhaust, but that's it, so hopefully switching to the 103s wouldn't be a bad thing. After all, some have said on here that they noticed a nice gain in MPGs, and for going 800+ miles, I think a bump in MPGs would be nice.
Or should I just stick with my current plugs (BOSCH Plat/Ir Fusion)?
