What kinds of differences did you guys notice after replacing yours....my car has 117k on it right now and i was thinking about replacing them before i possibly hit the track next week. id imagine the car would probably run cleaner emissions wise....maybe get better gas mileage....is that what i should expect? i dont think its going to make up for any power loss i may have on my current ones with this many miles right?
FWIW, I picked up the NTK's at summit racing for about $35 a piece and they work great. As far as improvements are concerned..........I noticed my gas mileage has improved quite a bit along with better throttle response.
