Xtreme-DI LF4 HPFP Assembly

Description

This unit starts as a brand new AC Delco HPFP assembly. The internal piston is replaced with AutoTech internals (11.66 mm. diameter). Then the unit is assembled, flow tested and broken in on Xtreme-DI’s in-house HPFP assembly test bench. The Xtreme-DI HPFP assembly increases flow capacity by 36% over stock. When used in conjunction with the Tapout fuel cam, flow capacity is increased by 64%!

Made in U.S.A.!
