BMW N20 Valve Spring Kit by Ferrea

Engineered to tackle common issues like binding, breakage, and valve float, Ferrea Valve Springs are ideal for maximizing your N20 engine's reliability and performance.

Combatting Valve Binding, Breakage, and Float for BMW N20 Performance

Valve binding can cause improper valve movement, risking severe engine damage. Breakage can lead to valves dropping into the combustion chamber, resulting in catastrophic failures. Valve float, often due to insufficient spring rates, leads to power loss and combustion inefficiencies at high RPMs. Ferrea Valve Springs effectively address these critical challenges, ensuring smooth valve operation under extreme conditions.

Built for High-Lift, High-RPM Applications

Ferrea valve springs are meticulously heat-treated and stress-relieved, providing the stability needed for high-lift cam profiles and high-RPM racing applications. This construction minimizes load loss and ensures long-lasting performance, making them the go-to choice for those pushing their BMW N20 to its limits, on and off the track.

For added reliability, Ferrea offers precision CNC-machined retainers, designed to provide superior strength and stability under rigorous racing conditions. Ferrea Spring Seat Locators, crafted from robust 4140 chromoly alloy, feature a hard Nitrided surface treatment for enhanced wear resistance and toughness, delivering maximum durability for your high-performance setup.

Upgrade to Ferrea Valve Springs for Optimal BMW N20 Engine Performance

Stock BMW N20 valve springs are insufficient for high-lift cams and high RPMs, resulting in valve float and reduced power output. Ferrea’s high-performance valve springs, constructed with advanced materials like chromoly steel, deliver increased spring pressure, ensuring improved engine response, power, and overall reliability.
