BMW Drivetrain Parts for BMW 3 Series E92 (2007-2013)

Maintain peak performance and extend the life of your transmission with the Bremmen Parts DCT Transmission Filter. Engineered to block harmful contaminants, this premium filter protects vital components such as solenoids and fluid passages, ensuring smooth and reliable operation.

A clogged or worn transmission filter can restrict fluid flow, leading to delayed shifts, harsh gear engagements, or even severe transmission failure. Replacing the filter during routine fluid service or after major component replacements like the clutch pack, pump, or fluid pan is critical to preserving your transmission’s performance.

Choose Bremmen Parts for a durable, high-quality solution designed specifically for your BMW’s dual-clutch transmission.

The drive shaft support bearing is essential for stabilizing the drive shaft and ensuring smooth, efficient power delivery. Over time, the rubber mount surrounding the bearing can degrade, leading to excessive drive shaft movement and noticeable vibrations.

If you notice a thudding or clunking noise during acceleration, especially coming from beneath the center console, a failed center support bearing is likely the cause. Bremmen Parts provides a reliable and affordable replacement solution, designed to restore your BMW’s performance and driving comfort.

This is a complete differential to change the gearing of a manual transmission E90/E92 325i, 328i, or 330i (not for xi models) to a 3.64 ratio final drive. The standard gearing on the manual transmission cars is 3.15 or 3.23, making this E90 diff significantly shorter. This diff is from a 330i automatic where the gear ratio has to be shorter to make up for the transmission gearing differences and extra weight. This will dramatically improve acceleration on any 325i, 328i or 330i INSTANTLY! If you are looking for better off-the-line or rolling acceleration, and are willing to sacrifice a little top-speed (some of us don't get up to 150mph), this is one of the best ways to achieve it with almost no downside. There are few things that can improve your 0-to-60 and 0-to-100 times as much as shorter gearing, and this differential is clearly a best "bang-for-buck" solution for dramatically better acceleration. Since this is an Original BMW part it carries the same BMW two year warranty as any other new part. So there's no need to take a chance on a used part from a private seller.

Changing gear ratio changes the RPM range for any given speed. Use the chart below for examples of speed vs RPM changes for the 3.64 diff.

Why 5th? Because 6th does not have the mechanical advantage to get past wind resistance at these speeds - it is more of a cruise/overdrive gear. Using 5th for comparison purposes is much more relevant than having to take into account wind direction, resistance, grade, elevation, tire sizing, etc. These numbers are for comparisons among gear ratios only, not to determine what your E90 will top out at.2006-2011 325i or 328i, 6-speed manual, stock 3.23 gears, 255/35-18" rear tires
