Engine torque arm insert - polyurethane. Under hard acceleration, your entire engine and transmission actually rotates due to compliance in the factory bushings. While the soft factory bushings do a good job of damping engine vibration, they can also create a rubbery, vague response in the vehicle's powertrain. Our torque arm insert works in concert with the OE rubber bushing. With the insert installed, you car's throttle response will feel better and your shifts will feel more crisp and defined, especially on manual transmission cars. Installs in 30 minutes with hand tools. Please note that polyurethane is not as compliant as rubber. As a result, you may notice a slight increase in ride harshess and engine vibration after installation. Polyurethane engine torque arm insert fits all engine and transmission configurations on the following vehicles: Audi A3 08-on Audi TT Mk2 2.0T 08.5-on Audi TT Mk2 3.2Q 09-on VW GTI/GLI 08-on VW R32 09-on \\ VW Jetta V 08-on VW Rabbit 08-on VW Passat B6 08-on VW Eos 08-on VW Tiguan 09-on Note : Audi and VW have changed the torque arm mount mid-production cycle.
