Athena Racing 330 series Cooper Ring cylinder head gasket set.
For specific high horsepower applications, engine performance can be significantly improved by using Athena Cooper Ring gaskets, that are supplied with INOX steel ring. This technology outperforms conventional fire ring solutions.
Cooper Rings are oversize (also fits for oversize bores).

Athena advantages |
|
|
Reinforced material |
Asbestos free composite raw material OE approved |
|
Stainless steel ring (AISI304) |
Separate stainless steel rings assure maximum sealing around cylinder bore also on NOS and/or turbo charged engine where boost is over 2 bars. No head and block machining required |
|
Silicon beading |
Silicon-based beading is applied on critical areas to improve sealing around all cooling water and oil passages |
