Review AUDI 20v Aan Valve Cylinder Head Cove fits S4 S6 C4 TURBO 1993–1995

Introducing the Audi 034 Motorsport 1993-1995 S4, S6, and C4 20V Turbo AAN Valve Cylinder Head Cover, a high-performance upgrade for your Quattro engine. This cylinder head cover, part number 034103475Q, is designed to provide superior protection and durability for your engine.

The OEM cylinder head cover is made of a standard plastic material that can crack or warp under high temperatures and boost pressures. In contrast, this aftermarket cylinder head cover from Audi 034 Motorsport is manufactured from robust billet aluminum. Its solid construction not only enhances the visual appeal of your engine bay but also ensures superior protection against the harsh conditions of high-performance driving.

One of the most significant advantages of this upgrade is its ability to accommodate the larger AAN (Avant Audi New) valves found in the high-performance versions of these engines. These larger valves are essential for increasing airflow and power output. By replacing the OEM cover with this Audi 034 Motorsport version, you can unlock the full potential of your engine without the need for extensive engine modifications.

Another notable feature of this cylinder head cover is its reinforced gasket surface. This design ensures a perfect seal between the cylinder head and the cover, preventing coolant leaks and maintaining proper engine cooling. Additionally, the cover's CNC-machined finish ensures a precise fit and easy installation.

In summary, the Audi 034 Motorsport 1993-1995 S4, S6, and C4 20V Turbo AAN Valve Cylinder Head Cover is an excellent upgrade for Quattro engine owners seeking improved protection, durability, and power potential. Its billet aluminum construction, compatibility with larger AAN valves, and reinforced gasket surface make it an essential addition to any high-performance Audi build.
