4G63 EVO 4-9 Exhaust Cam Sensor Housing Relocation Kit - CAS Relocation
Version 2 has landed.
Tired of burning cam sensors on your EVO? Sick of jury-rigged heat shields that fall apart after one heat cycle? The Ichiban Engineering 4G63 exhaust cam sensor relocation kit is the permanent fix, not another band-aid.
This billet relocation housing rotates your exhaust-side cam sensor 180° away from the exhaust manifold - out of the heat that's been cooking OEM sensors and aftermarket units alike since the day this platform existed. No more replacing a sensor every season because it sat six inches from an exhaust runner.
Designed with precision using 3D scans of an EVO 4G63 head, the housing fits seamlessly - no guesswork, no modification, no filing down a bracket to make it work.
Machined from 6061-T6 billet aluminum, this kit isn't a cast stopgap. It's lightweight, strong, and built to survive the demanding race and street conditions that keep frying the factory setup.
OEM relies on fragile gaskets and messy RTV that fail the moment heat cycles them enough times. Ours uses dual O-ring sealing on both sides - leak-free, maintenance-free, and done arguing with silicone.
