C4 New Aluminum Air Pump Delete Pulley 1985–1991

This smog pump delete kit lets you remove the weight and complexity of the factory pump while keeping the original belt routing. Built entirely from aluminum, it lightens your setup and removes the parasitic drag caused by the stock smog pump, giving your engine a little extra breathing room.

The machined aluminum finish looks great in any engine bay and is also ready for anodizing or powder coating. The kit includes new fasteners and spacers.
