Torque Solution Billet Mivec Exhaust Cam Gear Housing is made from 6061 T6 CNC Billet Aluminum. This is a must for any EVO X with upgraded valve springs, which causes the OEM cast cam gear housing to fail due to the extra spring pressure. Prevent damaging your engine when upgrading your valve train by adding our billet unit.
Please Note: To install you must transfer the factory phaser, gear, hardware, spring and retaining pin from the OEM cast cam gear.
