Where would one go about getting this MAF conversion kit?

 

Two places...I got mine at www.mass-air.com that ones pretty pricey and quite a bit more wiring involved. If your not good at wiring...I dont suggest it. But it does come with more performance parts. Or you can go with www.dunne-rite.com its quite a bit more affordable and easy, just plug it in and go. But theres less tuning and performance parts with theirs.
