Description
The factory intake valve on your TRX400EX will eventually wear, restricting airflow and compromising engine efficiency. This Hot Cams replacement restores optimal valve sealing while adding durability upgrades that handle sustained high-RPM performance. If you’re rebuilding your top end or running hard on the track, this is the valve that delivers consistent reliability.
Hot Cams engineered this intake valve with forged one-piece construction and precision machining to exceed OEM specifications. The nitride coating and induction-hardened stem resist wear far longer than standard valves, while the polished surface minimizes friction losses throughout the power band. Installation is straightforward—it’s compatible with your existing OEM valve keepers and requires no modifications.
