The VA Motorsports auxiliary radiators for the BMW S58 engine are built for drivers who push their M cars harder than the average Sunday cruise. Designed for the G87 M2, G80 and G81 M3, and G82 and G83 M4, these side-mounted radiators bring serious cooling muscle to a setup that—let’s be honest—starts to sweat under pressure.
Here’s the standout detail: a 30-percent increase in core volume compared to stock. That’s not just a number—it means more surface area, more coolant flow, and more headroom when temps start climbing. Whether you’re hammering track days or just enjoy stretching the car’s legs, this upgrade keeps things cooler, longer.
And smartly, each unit comes equipped with integrated steel mesh guards. These are built to take the hits—stones, road debris, bits of rubber—without choking off airflow. You won’t notice them doing their job, but they’ll be working every time your front wheels kick something up.
Fitment is clean and direct. No hacking, no fuss. These radiators bolt right in, using the factory mounts and connections. TIG-welded end tanks and a dense, efficient core make for a rugged build that holds up to both heat and real-world abuse.
Pair them with a tune or supporting mods, and you’ll get even more from them. Lower intake temps, more stable oil temps, and an engine that feels sharp pull after pull. It’s the kind of cooling upgrade that quietly earns its keep—no gimmicks, no extra noise, just real gains in durability and performance.
You won’t see these radiators once the bumper’s back on. But you’ll feel them—every time the car stays cool when the stock setup would’ve started to fade. And that’s the whole point.
