Anyone have any idea if these 2 parts are identical:

DR3Z-17F828-AA (Original Part # for BOSS diffuser)
DR3Z-17F828-BA (Aftermarket Part # for BOSS diffuser)
DR3Z-17F828-AB (Original Part # for GT500 diffuser (quad-tip exhaust cutouts))

They look to both be the Boss rear diffuser and there is like a $70-$80 difference in price. I know one is original equipment (the AA), and the other is listed as an accessory (the BA). I have seen numerous posts here and on other sites where people installed the AA part, has anyone ordered and installed the BA?? Trying to figure out if there is any legitimate reason to pay the extra $$$.

TIA

Talk to Tousley Ford parts. I've asked asked them questions like this to save money too. They are always helpful.

Yup, same part, basically. One was listed as an OEM piece, and as you correctly noted, was later released as an accessory.

Definetly not a bolt on. I had to remove the rear bumper and cut quite a bit off and cut 4 slots into it. Then it bolted on.

But I already answered the question???

Sorry some how I missed your post. Thank you

My local Ford dealer had no insight for the difference. I added the part number to my original post for the GT500 diffuser he gave me as well. I ordered the aftermarket part for an $80 savings from the original OEM part. One last question for anyone who has already done this, doe the diffuser come with any hardware or do I need to order seperately the mounting hardware i've seen in multiple other posts???

Thanks again

TheDivaDanielle

no hardware. really all you need is two push pins.

Went with the DR3Z-17F828-BA part. It came with almost all the harware (6 clips, 2 quick nut screws, 2 plasitc push rivet type fasteners, and only one of the special clips for the middle section). I was able to get the bumper off and save one of the original ones so it was all good:

I changed out the center panel and faux cap, tinted the taillights, bumper reflectors, and 3rd brake light. Also got an AM GT500 spolier. All thats left to do on the outside is lower her and start with the suspension mods.

Looks just like mine, where are you located?

These newer ('13 and up) diffusers look to be easier to install over the '11 and '12's, as getting the 3 tabs from the license plate area are a pain to push out when removing the old diffuser.

North side, Noblesville. Where are you located??

Carmel, not too far from 96th & Keystone... Ever go to Cars & Coffee Indy?

I ordered DR3Z-17F828-BA yesteday, so I can't wait to get this on mine.

Never even heard of it until I read about it in your SGM post, it's every Saturday? What time and where? Might have to check it out

MADSCOTSMAN

Awesome... The hardest part about the install is 1st, working up the nerve to cut on your car, and 2nd, actually cutting the rear bumper. I bought an electric body saw from harbor freight and went through 6 or 7 blades and had a heck of a time with that POS tool (Not sure what else to expect from HF tools though). I would definately recommend a decent quality air saw. Even though the bumper is plastic, it is not that easy to cut (melting plastic binds up the blade). I traced the guideline with a Sharpie so I could see it better and had to use a coping saw by hand on a few spots the electric saw just wouldn't cut through... Good Luck

It's at McAlister's at 96th & Meridian from 10-noon or so every Saturday. July 6th it's moving across the street to Another Broken Egg Cafe. I probably won't be out this weekend because I have a wedding to go to

MADSCOTSMAN

Cool, I might check it out next weekend, gotta work this Saturday.
