    Great Replacement

    You will need this when rebuilding your turbo, as this is the only o ring that does not come in the Mechanics Parts Cabinet kit.

    The previous owner of my truck had Ford put in a new turbo, after wondering why the truck lagged I pulled to turbo to find there were no o rings at all!!! This sealed it all up and I'm running way more boost with added wicked wheel 2. Thanks clay!
