Race-Spec Dual-Pass Oil Cooler
A high-performance oil cooler for the BMW E46 M3, developed with VF Engineering around a turbulated, heavy-duty bar-and-plate core built for durability under sustained load. The cast end tanks are fully TIG-welded rather than the OEM's mechanically jointed and tack-welded construction, which makes for a more reliable, longer-lasting cooler under track use. CSF has supplied radiators, oil coolers, and intercoolers to the US aftermarket for close to four decades and is an OE supplier itself, so every unit goes through hydrostatic, vacuum-decay, and life-cycle testing before it ships as a drop-in fit for the factory location.
Frequently asked
Does the Race-Spec Dual-Pass Oil Cooler fit my M3?
This listing is specific to the BMW M3 (E46). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Does it need modification to fit?
No, it's designed as a drop-in fit for the factory oil cooler location.
What makes the construction more durable than stock?
The cast end tanks are fully TIG-welded rather than the OEM's mechanically jointed and tack-welded design, which holds up better under repeated heat cycling.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
