I have a 04 Dakota 4x4 QC and I am contemplating on purchasing the new Helix Power Tower Plus Throttle Body Spacer. I currently have only a few small performance items added right now. They include Flowmaster Custom 2 1/2 in 4 Out exhaust system, Bosch Platinum 4 plugs, Fram Air Hog Air filter, and K&N Oil Filter running Mobil 1. By the way its a 4.7L and these little upgrades have made a noticible amount of hp increase but nothing drastic. I am looking for the throttle body spacer first before I go to the Fastman throttle bodies. Any input on the Helix Throttle body spacer would be greatly apreciated. I am new to this forum and it seems like a great bunch of people with lots of info, thanks for creating such a great forum.
