|
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 |
