034Motorsport is pleased to present our new Billet Aluminum Rear Differential Carrier Mount Insert Upgrade for the B6/B7 Audi A4/S4/RS4! The factory Audi rear differential carrier bushings have voids in the rubber damping medium, which results in excessive rear differential movement (twisting) under load. This movement allows for unwanted drivetrain slop (and sometimes clunks) that can be observed when accelerating, decelerating, and shifting.

These billet aluminum inserts are designed to fill the voids in the factory B6/B7 Audi A4/S4/RS4 rear differential carrier mounts, and limit rear differential movement without sacrificing ride quality or introducing any additional noise, vibration, or harshness into the cabin. By filling the voids in the factory mounts, these inserts eliminate the associated slop and ensures that you're experiencing smoother shifting and throttle transitions, and an improved driving experience.

Installation is very simple, can be performed in minutes, and is completely reversible.

Features:
  • CNC-Machined Billet Aluminum Construction with Clear Anodized Finish
  • Application-Specific Design Featuring Stainless Steel Securing Washers
  • Engineered to Fill Voids In Factory Rear Differential Mounts
  • Drastically Reduces Rear Differential Movement During Shifting, Acceleration, and Deceleration
  • Improves Shifting Feel, Resulting in Crisper Shifts
  • Will Not Cause Additional NVH Transfer Inside Cabin
  • Easy, Straightforward Installation Takes Minutes!
What's Included:
  • 034Motorsport Billet Aluminum Rear Differential Carrier Mount Insert Pair
  • High Strength Stainless Steel Securing Washer Pair

Perfect Fit for 2008 Prius
I bought this for my 2008 Prius to help with allergens since I drive with my dog often. I wanted something that fit right and actually improved the air inside the car. Installation took under 5 minutes with no tools, and it dropped in without any issues. The build quality feels solid, not flimsy. After installing it, the air smells cleaner and seems to reduce dust and allergens during drives. It hasn’t restricted airflow and is holding up well with daily use so far. Pros: Fit my 2008 Prius exactly with no adjustments I noticed cleaner air and fewer allergy issues while driving Took me less than 5 minutes to install with no tools Cons: A bit more expensive than basic filters I usually get

Good Enough
This doesn't fit precisely into place. You can see in the photo that the pleats just end with no frame on the sides to seal to the body of the housing. You can wiggle the end pleat into place but there's nothing holding it there so I don't know how long it will stay there. Not a big deal for me, but if you live on a dirt road, there could be enough air bypassing the filter that you may get a dusty car sooner. Price was fine, but I won't buy this filter again.
