Fitment and details
The factory heat exchanger cools the water that cools your charge air, and it is the first thing to heat soak on a tuned or upgraded-turbo car. CSF's replacement roughly doubles the core: two rows and 68 mm thick against the factory single row at 25 mm, and it still drops into the stock location. Comes with a metal rock guard and billet transmission cooler mounts.

Send us your VIN and we will confirm before it ships.
Install safety: only open the cooling system on a cold engine. The low temp circuit must be refilled and bled the way BMW specifies, or the charge air will run hot. Use BMW-approved coolant.
Verify fitment by VIN before ordering.
