Upgraded Throttle Body Actuator Gear Set - S65 / S85

Product Details

The factory plastic gears in BMW S65 and S85 throttle body actuators are notorious for premature wear due to mechanical stress, engine vibration, and heat cycling. Over time, this wear leads to excessive play, throttle response issues, and eventual failure. This can cause DME fault codes, limp mode, and DSC malfunctions. While replacing both throttle actuators is costly, even new OEM units will eventually suffer the same fate.

Thankfully, ECS has developed the ultimate solution for E9X M3, E60 M5, and E63/64 M6 owners! These Upgraded Throttle Body Actuator Gears are constructed of Teflon-reinforced nylon, significantly reducing friction and gear tooth wear for long-term reliability. Each gear comes pre-installed on a 4140 steel shaft, strengthening the assembly and ensuring a hassle-free installation. With this cost-effective and durable fix, you can eliminate throttle actuator failures for good!

Features & Benefits:

• Upgraded Teflon-reinforced nylon gears – Superior to factory plastic-on-plastic gears, reducing wear and extending lifespan.
• Pre-installed 4140 steel shafts – Increases durability and simplifies installation.
• Prevents common actuator failures – Resolves worn gear issues that cause CELs, limp mode, and DSC/DME errors.
• Cost-effective alternative to full actuator replacement – Saves hundreds in parts and labor.
• Factory-like fitment – Engineered for precise compatibility and long-term reliability.
• Built to withstand heat and mechanical stress – Ensures consistent throttle performance and extended service life.
