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 338058R
Gasket thickness: 1.30mm
Bore size: 87.50mm
|
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 |
