Fitment Note: Does not fit the E46 M3 (S54 engine) — the M3 requires a separate CSF radiator. Fits both manual and automatic transmission models, but automatic transmission vehicles will need to retain or add a separate external transmission oil cooler, as this radiator does not include an integrated ATF cooler.
Specs & Features
- All aluminum performance radiator
- Fits manual transmission and auto (auto requires separate oil cooler)
All OEM attaching components are reused, including the AC condenser, fan shroud, mounting brackets, and quick-connect hoses — no modifications are required. The thicker 42mm dual-row core may tighten clearance between the expansion tank and the accessory belt, but touching has not been reported as an issue on track-driven or Spec E46 builds.
Pairs well with:
- HPS Performance Silicone Radiator Hoses BMW E46 323i M52 2.5L (1999-2000) — 3-ply silicone hose upgrade to complement the new radiator on early M52-powered E46 models.
- HPS Silicone Radiator Hoses BMW E46 330i / 330xi M54 3.0L (2001-2005) — silicone hose upgrade to pair with the radiator on M54-powered 330i/330xi models. Additional HPS hose kits are available on Redline360 by engine and model year.
Product Description
CSF Radiators are made from military grade aluminum to surpass any other radiator on the market for quality and durability. Each radiator undergoes the most testing we've ever seen, with everything from burst pressure to wind tunnel testing, CSF demands the most out of their radiators to ensure they are the best performing and highest quality radiator you can buy. Each radiator 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 radiator, it's flawless.
CSF's B-Tube technology increases heat transfer surface area by approximately 15% over conventional oval tube radiators by using a seam-brazed B-shaped tube design that allows dual liquid laminar flow within the same space as a single tube. Each radiator is individually leak-tested and undergoes a 30-point inspection before shipping. Backed by a 2-year limited warranty from CSF.
CSF Radiators Feature:
- Drop in radiator requires no modification for install
- Designed with OE fitment specifications
- TIG welded military grade aluminum
- "B-Tube" technology keeps even the most demanding engines cool
- Undergoes leak, thermal cycle, burst, vibration and wind tunnel testing
- Ideal for any type of racing or daily use.
- "Show Stopper" mirror finish
