Product Overview

Cometic Gasket introduces the new StreetPro gasket kit line for the Import Automotive Market. StreetPro gasket kits offer the same unparalleled Cometic sealing technology, used in championship winning race cars around the world, in an affordable package.

StreetPro kits are sold separately as top and bottom end rebuild kits. In the top end kit you'll find everything you need for a head change, from the MLS head gaskets up to the induction gaskets. The bottom end (or conversion kit) will have everything you need to rebuild from the oil pan to the timing cover. Ordering the two kits together will give you every gasket and seal required for a complete rebuild of the motor from top to bottom.

Engine Gasket Set

For the majority of vehicles, Cometic gives you the economical option of ordering either the top-end or bottom-end gasket sets--and if you want a complete kit, you just have to order one of each. However, some engines, such as the Subaru EJ series, may require full replacement, Street Pro gasket kits are available with every gasket or seal you could possibly need when doing any level of engine work. That includes head gaskets, valve cover gaskets, spark plug O-rings, intake manifold gaskets, and more. If you're rebuilding a motor, or just like to have an assortment of replacement gaskets and seals on hand, these kits offer the most value for your dollar.
