BMW Drivetrain Parts for BMW 3 Series E46 (1999-2005)

ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.

Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.

For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.

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

Requires shorter flywheel bolts - 8x (P# 11227805885) - T#12322

Lightweight flywheels have proven themselves to be a worthwhile performance enhancement. But with the quicker throttle response and horsepower improvement comes one serious drawback: flywheel chatter. Without the dual-mass flywheel's rubber isolators, a lightweight aluminum flywheel has more rattle than stock. ECS has designed this flywheel using chrom-moly steel and it weighs almost ten pounds less than the stock DMF but not as extreme as full aluminum flywheels. The steel helps dampen vibration and noise so you get near-factory refinement and most of the benefits of a lightweight flywheel: quicker throttle response, better reliability, and more power to the wheels. This flywheel requires the E34 M5 sprung hub clutch kit.

Modern flywheels are built with additional components that are designed to dampen and minimize vibrations from the engine and transmission. Weight has increased and reliability has decreased. With additional weight more energy is required for it to move. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance. And with a single-mass flywheel the unreliable DMF design is eliminated.

Stock flywheel weight - 25.0lbs
ECS flywheel weight = 16.55lbs
