Subaru Race-Spec Throttle Spacers

Similar in concept to our street-spec spacers, we at OBX have designed a throttle spacer to fit the needs of the most hardcore enthusiast.
These new spacers have a number of ports that allow for different attachments. The bore size of this spacer is 60mm and is compatible with the factory throttle body. By using this part, it alleviates vacuum t-offs so you will never lose vacuum pressure to remote locations. The spacer provides 5 vacuum ports; 3 10/32" ports and 2 1/8" ports allowing hose ranging from 4mm up to 8mm which can be used for anything requiring vacuum from a fuel pressure regulator, blow off valve, waste gate, map sensor. It can also be used in conjunction with any nitrous kit.
