Product Description

The BLOX Racing BXCM-10104 Tuner Series HSL camshafts are built for B-series DOHC VTEC engines (B16A, B18C1, B18C5), using OEM-style lobe geometry paired with BLOX's high speed lift profile for a meaningful gain in top-end power and torque.

Because this is the HSL profile, it requires BLOX dual valve springs and titanium retainers (sold separately) to run correctly - factory valvetrain components aren't rated for the increased lift. It's best suited for enthusiasts building a naturally aspirated B-series engine for track or spirited street use, rather than a bolt-on upgrade for a stock valvetrain.
