Lower Air Deflector GT 2005-2009 is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Great Product! I recently up dated my front end with a new GT bumper cover and added the Deflector. I cant believe how much it tightened the whole front end up. Thanks CJ you guys ROCK!

Rated 5 out of 5 by from Nice quality piece When I bought my 08 Bullitt back in August, I didn't even realize this piece was missing from the front. I noticed after installing a front lip how weak/flimsy the bumper cover seemed to be an did a little research. Sure enough this is just the piece I needed to brace it. Unfortunately, it appears the original was torn off. None of the 7 original screws remained and of the 3 original "u-nuts" on the car, only 2 remained. Thankfully the 3 on the deflector come with the piece. My screws an u- nuts have been on backorder for a month now. I'm about ready to try an rig something but the way it mounts on the rear is tricky as there is no way to get a wrench up in there to hold a regular nut.

Other than ford, where can you get the hardware for this item?  The hardware has been on backorder from Ford.

Asked by: pjbsmith
Unfortunately Ford is going to be your best bet. You could potentially find something similar at your local Auto Parts or Hardware Store.

I am after this piece, plus the piece that would be on the leading edge that fits up inside the front bumper. Can I send you a picture of it?

Asked by: Johnny Mc
The pictures on the product pages are the only pictures we have, but they should be high quality enough to allow you to make your decision.

I bought an aftermarket one before that was extremely flimsy compared to the original (you could roll it up like a burrito ). The original is ver sturdy hard to bend plastic. Is the one as robust

Asked by: Windvielchris
Yes, this is a pretty high quality part that is quite durable.

How do I make this work with a GT500 front end? There is a 4" difference between the mount and the bumper cover.

Asked by: JarheadPJ
It won't fit a GT500, due to the different designs of the front ends. It's only for GTs, GT/CSs and Shelby GTs.

Lower Air Deflector GT 2005-2009 Video Transcript
By Bill Tumas: We’re here with a replacement factory lower air deflector fitting all 2005 through 2009 Mustang GTs. This deflector is a commonly damaged part on the bottom of 2005 through 2009 Mustang GTs. This will fit the GT, as well as the California Special. If you have a six cylinder Mustang and are doing conversion to a GT or California Special front bumper cover, you'll need this deflector as well. This deflector does not include hardware except for the four factory retainers here, but will install using the factory hardware found on all 2005 through 2009 Mustangs.
