Hello, new to the Bonnie-world, but not to CAI. I have removed stock airbox completely, and had a CAI custom made from a 3inch piece of stainless exhaust,bent to fit in the space theat the org. was in.Tipped witth a K&N 3in cone, drilled a hole to place sensor in place. Then had it powder coated, what a difference it makes. My mods are Jet 6-way chip, head-work, bottom-end freshed up, 3 in exhaust from engine back,hi-flow cat,Ultra-flow muffler, with ractive stainless tips.
