What's New

HHP Now Remanufacturing Injectors!

Since the beginning, HHP has always been concerned with quality - our aftermarket parts are more than aftermarket. They’re handpicked by our experts in the field, and with a combined 45-plus years of experience, we know what works and what doesn’t.

That’s why we have begun remanufacturing our own fuel injectors. From the time we receive a core part to when it’s packaged and sent for delivery, we ensure that only the highest standards are followed!
