Recently purchased a BBK CAI for my 2005 Mustang GT. I already have a BBK Throttle body and BBK X-Pipe, so I went for the BBK intake to complete my intake/exhaust system. Install is very easy. About 30 to 45 minutes. BBK is a quality product and very happy with my choice. Even though BBK says you don't need a tune, I would still recommend one if installing this item. There are many intakes out there, but if you want a great product (especially if you own a Mustang, go with this one)
Read the warranty carefully.
It came with a broken tp sensor which I installed unknowingly. It worked, even with the broken sensor, for about a week. After that period the truck refused to shift out of first gear. I made it home and it refused to crank. Had to call a tow then had it worked on. After all that I found out the sensor they sent me was defective. Make sure this is a product you want to take a chance on.
