Product Description

The factory allen hex cam bolts on Dual AVCS EJ25 engines are infamous for stripping out during removal, turning a routine timing job into a frustrating extraction project. This kit replaces all four intake and exhaust cam bolts with hardened steel, zinc-coated units featuring a 17mm hex head - a far more forgiving fastener to work with when it's time to pull the cams.

Whether you're doing routine maintenance or building toward bigger cams and internals, swapping to these bolts up front means one less headache the next time this engine comes apart. A simple, inexpensive insurance policy for anyone planning future work on a Dual AVCS STI.
