4-Vane, Pro Mod Vacuum Pump with mount and hardware.
MOR22643
$799.99

4-Vane, Pro Mod Vacuum Pump with mount and hardware.

Extra vacuum increases power by improving ring seal and preventing blow-by, intake-charge contamination and detonation; and by allowing the use of low-tension piston rings for less friction. Moroso's "purpose-built" racing pumps offer all these power advantages and more and are your best alternative over the passenger car "smog pumps" that are being offered by others for race applications. Moroso offers four different model pumps and all the accessories you'll need for your install. These pumps will suit any engine combination and requirement.
