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.

Universal High-Flow Air Filter

Oiled vs. Dry Filters — Which Is Right for You?

Oiled Filters

Offer slightly higher airflow for maximum performance

Require more frequent cleaning

Must be re-oiled after each cleaning

Long-term reusable design saves money over disposable paper filters

Dry Filters

Provide excellent airflow with minimal maintenance

Easily cleaned with warm, soapy water—no oiling required

Still flow significantly better than OE paper filters

Fully reusable and cost-effective

Both versions deliver superior performance over stock filters while offering the long-term benefit of reusability. Choose the option that best fits your maintenance style and performance goals.

This dual-cone intake for the 135/335/535 is similar to the enclosed carbon fiber intake but without the surrounding air box. If you love the look of the open filters and high-tech carbon fiber, this is the kit for you. High-flow cotton air filters connect to CAD engineered carbon fiber intake tubes for an improvement in air flow. The open filter layout releases more intake roar than the stock muffled intake.

135/335/535 ECS open DCI intake features -

• Designed and engineered using CAD technology for optimal flow and fitment
• Washable/reusable high flow cotton filters (pre-oiled)
• Stainless steel hardware
• Direct replacement for stock air box; integrates seamlessly with stock intake piping
• Beautiful and functional carbon fiber/e-fiberglass construction

The ECS Kohlefaser Luft-Technik (Carbon Fiber Air Technology) intake for the 135/335/535 is a beautifully crafted dual-cone intake with a glossy carbon fiber enclosure. Developed in-house using ECS's chassis dyno and state of the art laser scanning and 3D CAD technology, the N54 carbon airbox is a direct replacement for the stock system. Laser scanning allows ECS to produce a finished product that is a perfect fit to the engine bay. All tubing is also made from carbon fiber with each piece designed for optimal flow. The carbon fiber sandwiches a special heat-blocking fiberglass core, insulating the air box from engine bay heat. All of this combines to produce more power and torque over a wider RPM range - up to 13ft-lbs and 18hp when combined with a Cobb software tune, FMIC, and exhaust. And it looks amazing every time you open the hood.
