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.

Ensure optimal engine performance with the replacement of your vacuum system hoses. The vacuum system plays a crucial role in the engine's functionality, transforming it into an efficient pump that influences air-fuel mixture and combustion. Damaged vacuum hoses can lead to various performance issues, from rough idle to difficulties starting the engine. If you're experiencing these issues, it's time to upgrade to this plastic hose with a 2.3mm inner diameter. The hose is black, arrives in an 8-foot section, and can be easily cut to the desired size for a perfect fit.

Key Features:

• Engine Optimization: Replacing old hoses ensures the vacuum system operates at peak performance.
• 2.3mm Inner Diameter: Designed to meet specific engine requirements.
• Black Color: Blends seamlessly with the engine components.
• 8-Foot Section: Provides flexibility to cut the hose to the required length.
• Easy Installation: Upgrade without hassle for improved engine efficiency.

Upgrade your vacuum system with this high-quality plastic hose, addressing performance issues and ensuring your engine runs smoothly.

Ensure your vehicle maintains optimal fuel efficiency and performance by swiftly replacing the Mass Airflow Sensor (MAF). This crucial component regulates fuel delivery through injectors based on incoming air volume. A faulty MAF can significantly impact gas mileage and overall performance.

Gradual MAF failure often results in reduced fuel efficiency and performance degradation. Complete failure may cause stuttering and stalling, forcing the vehicle into a limp mode. A simple diagnostic test involves unplugging the MAF connector before starting the car; improved idling indicates a faulty MAF requiring replacement.

Failure to replace the MAF leads to excessive fuel consumption and inefficient burning, adversely affecting fuel economy. Opt for a Genuine BMW MAF replacement to ensure stock-quality performance and enhance vehicle efficiency.

Maxiumum Flow Pro5R Filter

11.75 hp and 10.50 lb/ft torque gain!

This intake kit replaces your restrictive factory air box. It features a 3-angle velocity stack adapter, heat-block molded intake tube, 1.6mm powder-coated steel heat shield, trim sealed to seal out hot engine air, and a custom aFe brand cotton filter.

This version uses aFe's highest flowing filter media, which uses a light oil gauze to filter out dirt and particulates while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.

By removing your stock intake air box, you are removing the most restrictive portion of your V8's intake system, increasing both horsepower and torque, improving acceleration as well as throttle response.
