Product Description

The CSF 3054 high-performance aluminum radiator is engineered as a direct replacement for select BMW E30 and E36 models, including the E36 M3 from 1988-1999. Featuring a heavy-duty 2-row, 42 mm thick B-Tube core and multi-louvered fins, it delivers approximately 25-30% improved cooling over stock units, ideal for spirited driving and track use :contentReference[oaicite:8]{index=8}.

Constructed using TIG-welded aluminum end tanks and CNC-machined connections, the CSF 3054 installs directly using all factory components - no modifications needed. Each radiator is individually pressure and leak tested and finished with either satin or polished end tanks, complete with a race-style drain plug.

Designed for both manual and automatic E36 models and manual-only E36 M3 variants, this radiator ensures reliable temperature control under demanding conditions. Fitment is confirmed through 1999; coverage beyond 1999 is unconfirmed at listing time.
