Mishimoto Lifetime Warranty
The 2021+ G80 M3's S58 engine, boasting over 45 years of heritage, impresses with near three-second 0-60 mph times and a power output exceeding 500 horsepower. However, as with each previous generation, there's potential for the G80 M3 to harness even more power. Bolt-on modifications, substantial turbochargers, and tuning can thrust the S58 beyond the 800 HP threshold, but achieving such power necessitates serious cooling. Enter Mishimoto's Performance Charge Air Cooler Manifold, an innovation engineered for high power outputs.
While the stock G80 M3 charge air cooler is adequate, it falters with its combination of intercooler and intake manifold design. The tube-and-fin core, crimped onto the thermoplastic plenum, is known to falter, with numerous units failing with a boost increase of just 3 lbs over stock. Mishimoto's solution is a resilient, cast aluminum manifold featuring a bar-and-plate core that's TIG-welded to withstand over 60 PSI of boost without strain.
Setting reliability aside, the potential performance benefits offered by the Mishimoto charge air cooler manifold are significant. Its core is 33 percent larger than the stock unit, and the manifold improves flow to each cylinder by an average of 14 percent. This, in conjunction with the enhanced cooling of the bar-and-plate core, leads to a reduced pressure drop and intake air temperatures reaching a mere 11-degrees above ambient even under heavy load. The lower plenum, designed via Computational Fluid Dynamics (CFD), integrates an internal diverter, ensuring complete core utilization and balanced flow distribution to each cylinder for optimal and safe fueling. The manifold's runners, cast and CNC-machined, accommodate factory seals through O-ring grooves, and an included fiber gasket insulates the runners from engine heat, providing further cooling.
For the extreme power levels at hand, a matching fuel supply is essential, hence the inclusion of provisions for port fuel injection. These include a billet fuel rail and anodized aluminum injector blanks to seal the injector ports when not needed. Precision-machined injector ports, featuring optimized geometry, ensure perfect air-fuel mixture without the need for drilling. The supplied PTFE -AN fuel lines and fittings, compatible with ethanol, tie into the stock fuel lines. Additionally, six nitrous ports that accept 1/8 or 1/16-NPT nozzles can be sealed when not in use.
Mishimoto's charge air cooler manifold promises not just performance but also easy integration. It fits just like the stock unit and includes brackets to organize your wiring, a mount for the standard engine cover, and custom EVAP lines for a smooth installation. A handy cutout in the plenum grants easy access to the oil filter without hampering flow. Like all Mishimoto offerings, this Performance Charge Air Cooler Manifold for the 2021+ BMW G80 M3 carries the Mishimoto Lifetime Warranty, assuring a lifetime of superior performance. So, if you're seeking to extract serious power from your S58 engine, look no further than the Mishimoto charge air cooler manifold.
