Powerflex PFF5-4020 Motor Mount Insert Set for BMW 8 Series G14 G15 G16 2018 onwards

Sharpen response and stabilise your driveline with this genuine Powerflex insert set. PFF5-4020 slots into the voids of the factory hydraulic mounts to control fore and aft movement, giving a more connected feel on the road with crisper throttle pick-up and cleaner gear changes. Ideal for fast-road use where you want a noticeable improvement without the harshness of full solid mounts.

• Part number: PFF5-4020
• Vehicle fitment: BMW 8 Series G14 Convertible, G15 Coupé, G16 Gran Coupé from 2018 onwards

• Kit contents: 2 inserts to treat both sides
• Diagram reference: 21
• Suits OE mount part numbers: 22112284817 and 22112284818

Why this upgrade works

• Limits engine rock under load for more direct power delivery
• Improves shift feel and drivability, especially on tuned or spirited road cars
• Keeps everyday refinement largely intact, with only a small increase in NVH typically at idle
• In-situ fitment possible, so you do not need to remove the mounts from the car
• Helps support and prolong the life of the original hydromounts

What our customers say

We have installed PFF5-4020 on customer 8 Series builds and the feedback has been consistently positive. Owners report tighter response, better on-off throttle control and a more planted feel without making the car uncompromising for daily use.
