I need the part number for the torx bolts that hold the front and rear engine under body (diffuser) panels on.

The bolt is part # 4G7Z-16163-AA. Be prepared for stupid pricing. My discount price was $5.06 each. It is a 6x1.0x25mm Torx bolt.

Thanks for the info...

The dealership that worked on this car before us stripped the heads on the Torx bolts. I dunno what they were using but the dealer sucks.

Use a T-27 Torx for all screws in the rear-most pan. For the mid-pan, the 6 screws on the outermost edge (3 on each side) that also attach the rocker panels are longer and use a T-30 Torx. I thought the manual even called for a T-25 somewhere - but that would be incorrect, and could lead to stripping of the heads.

Also you can go stainless as an option.

If you use stainless steel, make sure you use a very good thread lube (ARP Assembly Lube works great) in order to prevent galling and freezing the bolt to the threaded hole!

Thanks Ralphie, I forgot to mention that. I guess the rest of my post was not PC enough. :lol

Anytime that you place two dissimilar metals together you have to place a barrier between them. Also going into aluminum you have to be careful and hand thread them the first 1/4 of the way before you place a speed drive on them to prevent cross threading. I put a bit of white lithium on the threads just to be safe and to make it a bit easier next time no matter what faster is going into the underside of the car.

Is that a bit OCD? yes. but I also have never galled or stripped a fastner either. I enjoy tinkering on the cars as a way to vent stress and see some results. When you work a job that takes years to see the fruit of your efforts ... stuff like that really makes a difference .. or at least it does for me.

:thumbsup. A T25 on the pan bolts will do it. Make sure your using a 27
