PPE Performance Air-to-Water Intercooler with 3.5" Duct (Universal)

This is a PPE performance air-to-water intercooler with 3.5" duct connections and a no-side-mount layout. It’s a universal, fabrication-oriented piece meant for custom and swap applications rather than a specific truck.

An air-to-water core transfers heat from the charge air into a liquid circuit, which lets it deliver strong, consistent cooling in a smaller package than a comparable air-to-air unit. The 3.5" ducts match common charge-air tube sizing for easier plumbing.

This is a smart choice when frontal space is limited or when you want steadier intake temps on back-to-back pulls, where air-to-air setups tend to heat soak. It suits builders putting together their own boost plumbing.

Because it’s universal, you’ll need to supply the rest of the water circuit – pump, front heat exchanger, reservoir, and hoses – and mount the core to fit your build. It’s backed by a 3-year limited warranty.
