Don’t get overheated!

Just because you have fresh oil in the pan doesn’t mean you aren’t wearing out your critical engine parts. Overheated oil is thinner and breaks down faster than oil kept within its designed operating range, so are you ready to risk it all with a faulty or leaking oil cooler?

HHP is here to make sure you don’t have to take that risk. We offer premium aftermarket parts at up to 50% off OEM prices. And, while most believe aftermarket retailers sell cheap parts with zero warranty, packed in a beat-up box from who knows where, HHP is here to kick that stereotype to the curb. HHP provides engine oil coolers with a 2-year parts and labor warranty. How’s that for an aftermarket part?

We've got what you need to keep your cool.
