Description
Brian Crower Stage 2 N/A & High Boost Intake Camshaft – Honda K20 / K24
Precision CNC-ground from 8620 steel billet to deliver superior cylinder filling, extended high-RPM power, and maximum durability for naturally aspirated or high-boost K-series engines.
High-Performance K-Series Valvetrain Upgrade
Engineered specifically for dedicated Honda and Acura K-Series builders, the Brian Crower BC0042-2I Stage 2 Intake Camshaft is designed to maximize top-end power without sacrificing street drivability. Machined from premium 8620 aerospace-grade billet steel, this intake camshaft provides significantly increased rigidity under extreme engine speeds, effectively suppressing flex and valve float.
Ideal for naturally aspirated all-motor setups with 11.5:1+ compression ratios or forced induction builds running over 18 psi of boost, the BC0042-2I features an aggressive 304° advertised duration profile and .525″ (13.34 mm) gross valve lift. Advanced CNC grinding wheel techniques create faster ramp rates to optimize cylinder filling across high RPM ranges.
