BMW G42 2 Series Poly Motor Mount Inserts - PFF5-4020

Give your BMW G42 2 Series a tighter, more connected feel with this PFF5-4020 poly motor mount insert kit. By reinforcing the factory mount voids with a 70 Shore A yellow polyurethane insert, you cut down unwanted engine rock for crisper throttle response, cleaner upshifts and downshifts, and more consistent power delivery on the road.

Designed to sit neatly inside the original rubber mounts on the G42 platform, this upgrade adds control without the harshness of full solid mounts. It is an ideal choice for fast-road builds and daily-driven performance cars that want better drivetrain stability with only a small increase in vibration at idle.

Why enthusiasts choose this upgrade

• Part number: PFF5-4020
• Polyurethane insert kit for the BMW G42 2 Series from 2022
• 70A shore compound helps restrain engine movement while keeping comfort intact
• Fits into the OE mount voids for a precise, secure reinforcement
• On-car installation - no need to remove the engine mounts
• Sharper throttle response and more immediate torque transfer
• More precise gear changes and improved drivability
• Helps reduce drivetrain shunt and protects the life of factory mounts

What you will notice

Expect a more planted front end on and off throttle and improved shift feel as the engine is better controlled under load. A light rise in NVH may be noticeable at idle, which is typical when increasing mount stiffness, but the 70A rating strikes a sensible balance for spirited road use.
