installed new autozone plug wires yesterday to replaced the msd's. i have to say it seems like there is much more solid power with these new wires over the msd's, it could be me getting my hopes up or something i dunno, but it seems that way. also installed ported throttle body and i have a . noticeable increase in throttle response and the motor is getting way more air over stock. this isnt a mod that you can feel a huge difference in overall power but the assometer can tell a bit. IMO, worth the 80 bux
