PFF5-4020 and PFF5-4021 Engine Mount Insert Kits are an intermediate alternative to the BMW aluminium inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in our Yellow 70A durometer material, they are designed to fit the voiding of the OE mounts snuggly to restrict engine movement with a minimal increase in NVH, perfect for those with tuned road cars. Their design and flexibility also mean they can be fitted to the vehicle without removing the engine mounts themselves. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: - Sharper throttle response - Improved gear shifting - More direct power transfer - More balanced on/off throttle handling - Prolonged life of the OE mounts. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted. Fits N54, N55 and B58 engines only.

Upgrade Your Car with POWERFLEX Polyurethane Bushes!
Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication.
The material OEM bushes are manufactured from is a rubber compound containing natural products that deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry.
This in turn causes accelerated tyre wear, braking instability, and poor handling. This is the single biggest reason you can instantly tell the difference driving a three-year-old car compared to a showroom new one. However, even new cars will benefit from POWERFLEX bushes because of the superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.
With the technological advances of polyurethane, it has been possible to overcome the common problem associated with harder bushes which is increased noise. By correctly engineering the polyurethane compound, bushes can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties.
