all those spacers do really is lower your intake temp a little. Yes, it would help, but probably not something your going to notice. Have you considered nitrous? nothing crazy...just a 50-100 shot :icon16:

Don't get the spacers. Get some new plugs/wires and an underdrive pulley or something. The spacers are near worthless on fuel injected cars. While they do lower plenum temps a bit, IMO they just aren't worth the cash. Another cheap option would be a small wetshot of nitrous. You can use it when you need it.
