Hallman ES Manual Boost Controller - Black

This is an official Hallman manual boost controller. Just like RTM Racing's own MBC, the Hallman MBC is a ball and spring style of boost controller. We like to think that, functionally, both the RTM and the Hallman are identical. We will concede, however, that the Hallman unit is a bit fancier esthetically.

The Hallman ES is machined out of billet aluminum. Also included is a length of vacuum line, cable wraps for mounting and complete installation instructions.
