I bought the ignition ignition equalizer from monstermotorworks.com, and yeah, it was pretty expensive, but I do recommend making your own kit. The November 2006 issue of Import Tuner shows you how you can make your own kit for a few bucks. The ignition equalizer is pretty much an expensive grounding kit, which you can get one on ebay for like $20. I can say that it did help my throttle response a little, and it did help my iddle a bit as well. Do I regret buying my ignition equalizer? Well, I only regret paying so much for something I could have made myself, but it does look nicer than anything I would have made.
