If you want to eliminate potential vacuum leaks on your K swapped car equipped with a B series 74mm throttle body, this gasket is for you. We've deleted the unnecessary air passages found on all other aftermarket gaskets, and have also built these out of steel reinforced 0.100" material to ensure a perfect seal every time. 

Note: as of July 1, 2018, all throttle bodies and Ultimate Swap Packages come standard with this gasket.
