Powerflex PFF5-4020 Engine/Motor Mount Insert Bush/Bushing Kit for BMW 2 Series F22/F23 - Road Series Polyurethane 70A Yellow - Torque Mount Support, Uprated Fast Road Performance - Replaces OE 22112284817 22112284818

Uprated Motor Mount Insert Set for BMW F22 F23 - Part No. PFF5-4020

Give your BMW 2 Series a sharper, more connected feel with this high quality motor mount insert set. Manufactured in durable yellow polyurethane with a 70A shore hardness, these insert bushes reinforce the factory mount voids to cut excessive engine movement, improve throttle pick up and deliver crisper gearchanges with only a modest increase in noise, vibration and harshness. A brilliant fast road upgrade for drivers who want better response without the harshness of full solid mounts.

What you will feel

• More immediate throttle reaction and tighter drivetrain control
• Improved shift precision and consistency under load
• More direct power delivery and reduced engine rock on acceleration and braking
• More composed handling on and off throttle, with better traction out of corners
• Helps extend the life of the factory rubber mounts by limiting excessive movement

Why this poly bush insert kit works

These inserts fill the cavities in the original engine mount, acting as a torque mount reinforcement that limits fore-aft movement of the powertrain. You keep everyday refinement while gaining stability for spirited driving, remaps and fast road setups. Ideal if you want an intermediate solution between stock rubber and very stiff full replacement mounts.
