Athena Racing 338 series multilayer steel (MLS) cylinder head gasket.
Athena MLS gaskets are designed to suit the requirements of today’s competition engines offering enhanced sealing compared to the OEM product.
The gaskets are assembled from 2-5 layers of high quality stainless and spring steels.
Part number 338248R
Gasket thickness: 1.30mm
Bore size: 84.00mm
|
Part number starting with 338 |
|
|
Athena advantages |
|
|
Optimized radius embossing shape |
The round shape of the embossing increases sealing on cylinder bore, oil and cooling water passages and improves spring back strength |
|
Advanced stopper technology |
State of the technology enhances sealing pressure around the cylinder. Highest sealing properties in high power engines |
|
Coating technology |
Designed & engineered by Athena the special coating applied on steel surfaces, improves temperature resistance & reliability of the head gasket |

Athena Racing 330 series Cooper Ring cylinder head gasket.
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).
Part number: 330009R
Gasket thickness: 1.80mm
Bore size: 77.50mm
|
Part number starting with 330 |
|
|
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 |
