CAT Cams Camshaft Set, BMW N55

New & Exclusive to 5150 AutoSport: CAT Cams Camshaft Set for BMW N55

Maximize the Performance of Your BMW N55 Engine with CAT Cams Camshafts

The BMW N55 engine, produced from 2009 to 2019, stands out for its blend of power, efficiency, and tunability, serving as the heart of many iconic BMW models. With CAT Cams’ precision-engineered camshafts, now available exclusively through 5150 AutoSport, you can take your N55-powered vehicle to the next level. Whether you’re building for street performance or preparing for track days, these camshafts offer the power gains and throttle response needed to push your N55 to its limits.

Precision-Tuned Performance for Your N55 Build

CAT Cams camshafts are designed as a direct fit for the N55 engine, ensuring seamless installation. However, performance software tuning is required to fully optimize your setup. We have successfully collaborated with some of the industry’s top tuners, including Halim from HCPerformance, who has developed custom software for the N55. His tuning solutions maintain factory-like idle and drivability even with aggressive cam profiles while keeping Valvetronic and Dual VANOS fully functional. With an aftermarket throttle body, the Valvetronic system can also be locked open, providing even more control over your build.

Key Features:

• Direct-fit camshaft set for BMW N55 engines
• Optimized for stock and modified builds, including forced induction setups
• Improves power output, throttle response, and efficiency
• Maintains factory-like idle and full use of Valvetronic and Dual VANOS systems
• Compatible with custom tuning software from HCPerformance
• Perfect for street cars, track builds, or high-performance applications

Recommended Use:

For best results, we recommend installing these camshafts alongside other performance upgrades such as a fortified engine block, upgraded turbos, and improved fueling components. Whether you're aiming for higher horsepower or enhanced responsiveness, these camshafts complete your N55 engine build with reliable, long-lasting performance.

Built on Expertise and Engineering Excellence

Since 1989, CAT Cams has led the way in producing high-quality camshafts with cutting-edge technology. Each camshaft grind reflects decades of experience and precision, ensuring optimal performance and durability. With their expertise, the N55 camshaft set from CAT Cams delivers the reliability and performance enthusiasts demand.

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.
