This BSG (15-700-139) engine mount is produced for the 4-cylinder (M43, N40, N42, N45, N46) gasoline engines found in the BMW 3 Series E46 (1998-2005) models 316i and 318i. It absorbs vibrations at the point where the engine connects to the chassis, preventing noise and shaking from entering the cabin. Replacing worn or torn mounts restores vehicle comfort to factory settings.
- Wide Compatibility: Compatible with all old type (M43) and new generation (N42/N46) 4-cylinder gasoline engines in the E46 chassis.
- Hydraulic Structure: The oil-filled structure or reinforced rubber (depending on the model) dampens engine vibrations to the maximum level.
- Right/Left Compatible: This part is not directional; it can be mounted on both the right and left sides of the engine.
- Comfort Improvement: Especially reduces vibrations felt in the steering wheel and seat at idle (when waiting at a red light).

Frequently Asked Questions (FAQ)
Does it fit 320i / 325i / 330i (6 Cylinder) vehicles?
NO, IT DOES NOT FIT! The mounts for 6-cylinder (M52, M54) engines are completely different and have right-left orientations. This product is only for 4-cylinder E46s.
Are the Right and Left different?
No. In the E46 4-cylinder group (316i and 318i), the right and left engine mounts are the same. You can order this product for both sides.
Is the "thud" sound at startup caused by this?
If you hear a "thud" sound from the engine compartment when you suddenly press and release the gas or during gear shifts, your engine mounts may be broken. They need to be replaced.
