Athena Cut Ring Racing Head Gasket for Audi RS3 TT-RS 2.5L 20v TFSI 330117R

The Athena Cut Ring Racing Head Gasket is designed for high horsepower engine applications, offering advanced combustion sealing even under extreme pressure. This model, featuring a diameter of 83.50mm, is ideal for boosted engines where reliability and endurance are critical—especially under 2+ bar of boost or when using nitrous oxide (NOS).

Key Features

• Stainless Steel Cut Rings (AISI 304): Separate rings provide maximum sealing efficiency around the cylinder bore, even under extreme boost and NOS usage.

• Reinforced Core Material (M0115): OE-approved, asbestos-free composite material offering excellent mechanical and thermal resistance.

• No Machining Required: Designed for direct fitment without the need for cylinder head or block modifications.

• Silicone Beading: Applied to key sealing zones to enhance protection around oil and coolant passages.

• Surface Treatment: High-stress areas are coated with PTFE or special silicone layers to improve micro-sealing and prevent sticking or thermal breakdown.

Installation Notes

• Ensure that the ring engravings are facing the engine head during installation.

• Each gasket undergoes precise pressing, silicone bead application, and finishing to meet flatness tolerances and durability requirements.

• Manual refinement ensures correct fitment of the stainless steel ring insert.

Athena’s proprietary INOX fire ring technology significantly enhances combustion sealing over conventional and copper ring gaskets—making it the ideal choice for extreme performance builds.
