MIA's Description

The Brian Crower Stage 3 camshaft is designed for street use with built bottom ends. It offers a noticeable lope at idle and is optimized for stock or slightly higher compression in naturally aspirated cars. For turbocharged applications, it focuses on longer exhaust duration for top-end power production, moving peak torque and horsepower higher in the RPM range. Valvetrain upgrades and ECU tuning are required for optimal performance.
