Product Details

Sealed Power E-299K is part of the brand’s vintage component coverage for engines more than 35 years old.

This part number, E-299K, is commonly searched for classic Pontiac engine rebuilds and standard-size piston ring replacement.

This part cross-references Eastern Catalytic 40784 for the same application.
