Original Product Notes

We kept your original imported notes here for reference.

If you’ve been following along with CSF’s products, you’ll see that we emerged in the AMG market with our W205 C63 AMG Heat Exchanger – it quickly became a #1 seller, so we took its momentum and created a  full Mercedes-Benz AMG cooling line. CSF has mastered the charge-air cooling system, like the one found in new AMG models. The system features a water circuit that flows through the vehicle’s charge cooler(s) and a heat exchanger, which uses the water to cool the compressed air. Upgrading to a larger, more efficient Heat Exchanger effects the entire rest of the charge-air cooling system – lowering IATs (intake air temperatures), thus creating cooler, denser air for increased power and an improvement in heat soak reduction.

Bill's Take
CSF radiators and intercoolers really impress me. They do an amazing job of keeping everything cool, even when you're pushing the limits on the track or during some spirited driving. I trust their products completely—they’ve always performed like a champ for me. Plus, the quality and fitment are top-notch, making them an easy go-to for any build. You really can’t go wrong with CSF!
