Man I didn't expect such a response. Well, the CAI my mechanic is working on is based off the wepon-R because that is what Leon already has. All it consists of is a mandrel bent pipe going from the Weapon R to the inside of the pasenger side fender. Yes, this does include an AEM bypass valve. I see no reason why I can have them made for other filters, as long as the diameter is the same. Leon is suppose to go in soon to get some measurememts done. After that I shoud have a price for all of you. Keep your eyes open. This is happening!
