CAT Cams Camshaft Set BMW S55

 The BMW S55, produced from 2014 to 2020, delivers impressive power and efficiency from factory, making it a formidable base for building a high performance F80 M3 / F82 M4 / F87 M2 Comp, with significant power and tuning potential. When combined with performance modifications and a fortified engine block, CAT Cams Camshafts will complete your competition engine build, reliably providing improved power output and efficiency.

Please note that these cams are a direct fit for the S55 engine, however, software tuning is required. We work with many talented tuners, however, Halim of HC Performance has been able to develop a software for the S55 engine that is able to maintain factory idle and drivability, even with these aggressive cams and performance gains. Still can maintain full use of Valvetronic and Dual VANOS. Can run Valvetronic locked in full open position when using an aftermarket throttle body.

Established in 1989, CAT Cams combines decades of engineering and experience with state of the art machinery and precision to produce some of the highest quality camshafts on the market.

For optimal performance and reliability, 5150 strongly advises replacing your valve springs with your camshafts, even with mild camshaft upgrades. This essential step acts as a preventive measure against potential piston-to-valve contact during instances of over-revving or mis-shifts. By taking this proactive approach, we prioritize your engine's well-being and ensure that you experience the highest levels of performance without compromising on reliability.
