034Motorsport Silicone Hose, B5 Audi S4 2.7T After Run Auxiliary Coolant Pump Delete
This silicone hose deletes the after-run auxiliary coolant pump on Audi 2.7T engines with the APB engine code, as listed for the B5 S4 and RS4 and the C5 A6 and Allroad. 034Motorsport explains that the factory plastic after-run pump is prone to leaking and can even burst, and because it sits under the intake manifold it can take hours to replace. The brand says high-horsepower cars do not need the pump if the engine is cooled down sensibly, while cars that do need it are better served by relocating it somewhere easier to reach. The hose is made from multi-ply reinforced silicone and comes with two hose clamps, and 034Motorsport warns that simply plugging the factory lines would stop coolant flowing through the turbos.
