Boundary Honda L15 B7 1.5L I4 MartenWear Treated Billet Oil Pump Gear - L15B7-OPG-M

Boundary oil pump gears are 100% manufactured in our Dallas, Texas production facility. We start by quenching our chromoly billets from extreme heat and then temper it to a tough indestructible core. After machining, we apply our ColdFlow finishing process and complete it to a Mirror Finish. What does all this give you? It gives you a pump with stability over 9000 RPM, proven over 1000whp, with higher efficiency, less friction, and backed by one of the industry’s best warranties.
