Ensure the longevity of your BMW's drivetrain with ECS Tuning's Magnetic Plugs. These plugs are meticulously engineered in-house to provide a perfect fit and feature a permanent magnet attached to the plug body. The magnet effectively attracts and captures tiny abrasive and ferrous metal particles, preventing their circulation through lubrication systems. Metal particles can accumulate due to various conditions such as normal wear, machining operations, casting flaws, and stress usage, leading to excessive wear of vital components. ECS Tuning's Magnetic Plugs help alleviate this concern by trapping these particles, thus safeguarding the internal components of your drivetrain. With a convenient 17mm hex head design, these plugs eliminate the need for special tools required for OEM plugs.

Key Benefits:

  • Removes abrasive metal particles from drivetrain fluid
  • Prevents excessive wear to internal components
  • Meticulously engineered for a perfect fit
  • Features a permanent magnet for efficient particle capture
  • Convenient 17mm hex head design for easy installation

The ZF 320z S5D is a common swap choice among BMW enthusiasts due to its reliable and robust nature. Unfortunately, it does have a weakness. The detent pins and springs that live inside of the transmission are known to wear down over time, often causing the shift lever to lean towards the 5th gear position when in neutral.

This full-service kit consists of everything you need to replace the failing detents in your ZF transmission. The kit contains only Genuine ZF components, all of which are sure to provide you with smooth shifting and operation for years to come.

This kit includes the following items:

3 Shift Pin Kits - 23117525048
2 Slide Bushings - 23117533395
2 Gearbox sealing lids - 23311224825
1 Shifter detent pin - 23311224849
1 Shifter detent pin - 23317502165
2 Lock Rings - 23317531374
3 Spring Retention Plates - 23317637524
5 Detent Drift/Punch Tools - 054834LA01AKT
Remedying the ZF's detent issue is a must for any enthusiast planning to get the most out of their transmission. Proper centering is essential for quick and smooth shifting, both being desirable features in any application. This kit is easy to install with several DIY guides existing online. A set of "drift" tools are included for proper installation.

A sloppy shifter is one of the common complaints of older BMWs. In addition to the shifter linkage the transmission mounts contribute to rough and clunky shifting. BMW transmission mounts are rubber and get softer over time. This allows the transmission to dance around which changes the geometry of the shift linkage and could make it harder to shift. These urethane transmission bushings are stiffer than the stock rubber mounts and won't let the transmission shift around as much. The round design also has more surface area than the stock mounts which helps spread the load. Because the urethane is stiffer, expect more vibration to make its way into the shift lever area. Engine motor mounts should also be considered as a cause for driveline vibration, transmission movement, and poor shifting. Consider replacing your motor mounts at the same time as your tranny mounts.

Price is for the pair of transmission mounts with hardware.

Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Automatic transmission Level II kit contains what you need to do an automatic transmission fluid and filter service. For limited time includes a FREE bottle of Redline WaterWetter®! WaterWetter® is a unique wetting agent that reduces coolant temperatures by as much as 30°F. Pour it into your cooling system to provide rust and corrosion protection in plain water for racing engines, and to improve coolant heat transfer properties. Add it to new or used antifreeze to improve the heat transfer of both ethylene and propylene glycol antifreeze/coolants. Compatible with aluminum, cast iron, copper, brass and bronze components. Kit Includes: Automatic transmission filter with hardware Oil pan gasket Drain plug with sealing washer Fill plug with sealing washer 8 quarts Redline D4 automatic transmission fluid FREE bottle of Redline WaterWetter®
