need LID
almost all of the aftermarket lids produce pretty much the same power according to a dyno flog i seen in a magazine so fitment is pretty much what you want to look for but since they are plastic that can can change from the same manufacturer.i like the looks of the slp lid.

That article was odd. The MTI lid showed the best MPH at the track, but had some of the lowest comparitive numbers on the dyno (along with the G2 lid). The SLP, TSP, QMP, and Whisper lids all put down numbers ~5hp higher than the MTI.
