An industry-leading reputation and overwhelming success with BMW cooling has made CSF the #1 cooling choice for the B58 power G2X M340i/M440i and G42 M240i. CSF continues to lead the way in G2X/G42 cooling, adding another product to the best-selling B58 cooling suite. With many motorsports teams and race enthusiasts now pushing over 1000 horsepower, the B58 is seeing oil temperatures well above normal. Once oil temperatures pass a safe limit, the G2X/G42 will go into limp mode. Needless to say, this can ruin a race, track session, or your overall driving fun in general. CSF is here to keep your B58 running at peak performance.

Whether you're building a dedicated track weapon or upgrading your street machine for ultimate reliability, unsprung and upper-chassis weight is the enemy of performance. Positioned high up in the engine bay or rear corners, a heavy factory battery negatively impacts your car's center of gravity.
