Athena Racing 330-Serie Cooper Ring Zylinderkopfdichtung.
Für spezifische Hochpferdestärken Motorleistungen erheblich durch den Einsatz Athena Cooper Ring Dichtungen verbessert werden, die mit INOX Stahlring geliefert werden. Diese Technologie bietet gegenüber herkömmlichen Feuerring Lösungen.
Cooper Rings sind Übermaß (auch fit für übergroße Bohrungen).

Athena Vorteile
Verstärktes Material	OE genehmigt Asbestfreie Verbund Rohstof
Edelstahlringen (AISI304)	Einzelne Edelstahlringe gewährleisten maximale Besiegelung um die Zylinderbohrungen, unter extremen Bedingungen, auch mit dem NOS-System und/oder Turbo-Aufladung, wenn die MLS Dichtung unfähig abgedichtet Brennkammer arbeitet. Zylinderkopf und Motorblock benötigt keine speziellen Behandlungen.
Silikon Beading	Silikon Beading wird auf kritische Bereiche angewendet zu verbessern Abdichten um alle Kühlwasser- und Ölkanäle.

Bohrungsdurchmesser - 82.50mm
Dicke - 1.22mm
Reinz Teilenummer - 61-31955-10
OE Teilenummern - 058 103 383 Q, 058 103 383 M, 06A 103 383 AK, 058 103 383 K, 058 103 383 H

Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to thematerial structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip.

The Super Alloy Engine valves represent the highest level of sophistication in valve technology. These valves are designed to handle the extreme heat requirements and punishment of today’s Nitro Fuels, Supercharged, Turbocharged, Nitrous Oxide, and Marine race motors.
