034Motorsport Density Line Engine Mount for Audi A4, A5, Q5, and allroad (2009–2016)

Sold one at a time, with two required per car, this 034Motorsport Density Line engine mount replaces a factory engine mount on 2009–2016 Audi A4, A5, Q5, and allroad models. The mount is void-free and fluid-free, using a 50 durometer rubber damping medium chosen to limit noise and vibration transfer into the cabin. Removing the voids and fluid takes out the slop of the factory mounts, which 034Motorsport says sharpens shifting feel and overall driving response. The mount comes in two densities tied to engine size. The Track Density mount is meant for the B8 2.0 TFSI four-cylinder, and the Street Density mount is meant for the six-cylinder engines. It does not fit 3.0 TDI vehicles. The mount is made in the United States.

034Motorsport parts sold by PMB Performance carry a 24-month warranty.

Each mount takes the place of one factory Audi engine mount. Audi used several numbers on these cars, including 8R0 198 381 B, 8R0 199 381 C, 8R0 199 381 AK, 8R0 199 381 G, 8R0 199 381 AL, 8R0 199 381 AD, and 8R0 199 381 AE. An engine mount holds the engine and transmission to the subframe and absorbs vibration, so as the rubber ages the engine rocks more under throttle and braking and more vibration reaches the cabin. Because both sides carry the engine together, order two mounts so the left and right match in rate. 034Motorsport, founded in 2005, designs, tests, and builds its parts in-house at its Fremont, California, facility.

Installation & Tuning Notes

034Motorsport recommends installing its Transmission Mount Insert along with these engine mounts to further limit drivetrain movement, noting a slight increase in noise and vibration with that combination.

Common Questions

Do I get both engine mounts in one order?
No. This mount is sold individually, and one vehicle needs two.

What signs point to worn factory engine mounts?
Engine and drivetrain vibration, and the engine rocking during gear changes or under braking.

PMB Performance carries the Density Line mount for drivers who want a firmer, more direct drivetrain.

Fitment & Compatibility

Check the fitment table below for your exact model and year. Confirm your engine before ordering, since the four-cylinder and six-cylinder engines take different mount densities. Send us your VIN and we will confirm fit.
