Anyone who’s ever worked on an engine, taken a class in physics or just played with incandescent lightbulbs has experienced the simple principle: when you generate power, you generate heat. But when you’re pushing the limits on the track, the last thing you want is for heat to force you to the garage. After all, you built a race car, not an oven. With our selection of cooling system components, you’ll be able to stay hot on the track and save the barbeque for the post-race celebration.

The radiator is the heart of any vehicle’s cooling system, and we carry Mishimoto radiators, Koyo radiators, Skunk2 radiators and more for a variety of turbocharged and competition vehicles. Naturally aspirated engines will run cooler and more efficiently when you install these direct-fit performance radiators. Made from lightweight durable aluminum, they’re designed to dissipate heat while reducing weight and holding up to the occasional bump or scrape. We also have a full inventory of radiator fans, hoses, caps and cooling plates to further increase coolant and air flow or replace damaged hardware.

A turbocharged engine may need a little more cooling power, and a Cusco or APR Cooling Plate will supercool your Evo VIII or Evo IX while bolting right into your stock location. Our replacement water pumps will keep coolant flowing throughout your engine thanks to specially formed housing and unitized seals. You can also start the coolant flow sooner by using a Mishimoto racing thermostat that opens up at lower temperature than their OEM counterpart. Fill it up with premium antifreeze and additives that promote thermal transfer while protecting against corrosion and build-up.

Modern Automotive Performance has a staff full of car enthusiasts who know how to play it cool even when they’re red-hot. Just call or email and they’ll be happy to help you find the right parts to do the same. From hoses to bumper heat shields, you’ll run faster and longer by using our automotive cooling components and accessories.
