CSF Heat Exchangers are made from military grade aluminum to surpass any other cooler on the market for quality and durability. Each cooler undergoes the most testing we've ever seen, with everything from burst pressure to wind tunnel testing, CSF demands the most out of their coolers to ensure they are the best performing and highest quality cooler you can buy. Each exchanger is designed to have drop in fitment, and require no modifications for installation. CSF even ensures their packaging is the best. Each package is built to withstand a 10 foot drop to make sure that when you get your heat exchanger, it's flawless.
