CSF Cooling | High-Performance Radiators & Intercoolers

Where to buy CSF in Australia: Chicane Australia sells CSF radiators, heat exchangers, transmission and engine oil coolers and a billet air-to-air manifold, and ships Australia-wide from the NSW Central Coast. The current range is built for the B58 six in the Toyota GR Supra (A90) and G-chassis BMWs, the S58 in the BMW M2 (G87), M3 (G80) and M4 (G82), and the Honda Civic Type R (FL5). Most CSF listings ship in 3 to 5 days, while the FL5 radiator has a 4 week lead time.

CSF is a US cooling specialist known for its B-Tube radiator core, which CSF says gives about 15% more heat transfer surface than a standard oval tube, and for fully TIG-welded aluminium construction in place of plastic end tanks.

Why CSF

CSF's B-Tube design uses a single-piece aluminium tube shaped like a "B" instead of a traditional oval tube. CSF states the profile adds about 15% more surface area for heat transfer while keeping the core strong enough for TIG-welded aluminium tanks rather than the plastic tanks fitted from factory. Plastic end tanks are a common long-term failure point on cars used hard, which is why an all-aluminium replacement suits cars doing regular circuit work or running more power.

Choosing the Right Part

Match the engine code first. B58 parts suit the GR Supra and B58 BMWs, while S58 parts suit the M2, M3 and M4. On these air-to-water cars, heat soak shows up first as rising intake temperatures, so the heat exchanger is the usual first upgrade: CSF quotes up to 22°C lower intake temperatures than the factory unit for its B58 heat exchanger. Transmission coolers suit tuned or track-driven cars where gearbox oil temperatures climb and shifts slow down. On the FL5, CSF built its oil cooler kit after recording oil temperatures above 135°C on track. The No Limit manifold is for race and motorsport use only.

Installation & What You'll Need

Most CSF parts use factory mounting points and OEM-style connections. The B58 auxiliary radiators, for example, fit either side without modification and use quick-connect fittings. Plan for fresh coolant or transmission fluid of the correct specification and a proper bleed after fitting, and read the notes on each listing for anything sold separately. Installation by a professional is recommended.

FAQ

Where can I buy CSF radiators in Australia?

Chicane Australia sells CSF radiators, heat exchangers and oil coolers and ships Australia-wide from the NSW Central Coast. Shop by vehicle above, search by CSF part number such as 8215 or 8221, or contact our team to match a part to your exact model year.

What does the CSF B-Tube design do?

It replaces the standard oval tube with a single-piece aluminium tube shaped like a "B". CSF says the profile gives about 15% more surface area for heat transfer than a standard tube, while supporting a fully TIG-welded aluminium core.

Which CSF parts suit the BMW M2, M3 and M4?

For the S58 G8X cars we list the front mount heat exchanger (CSF #8215), the Race-Spec dual core ZF8 transmission oil cooler (CSF #8221) and the No Limit billet air-to-air manifold (SKU 8402), which is for race and motorsport use only.

Which CSF radiator and oil cooler suit the Civic Type R FL5?

We list the CSF high-performance radiator, with a 2-row 42mm aluminium core and B-Tube technology, and the racing dual engine oil cooler kit. The radiator has a 4 week lead time.

Do the B58 parts suit both the GR Supra and BMWs?

Yes. The auxiliary radiator, heat exchanger and transmission oil cooler are listed for the Toyota GR Supra (A90) and B58 BMWs such as the M240i (G42), M340i (G20) and Z4 (G29). Check the listing against your exact model before ordering.
