A rattling noise from the top of the engine, a check engine light with camshaft or timing-related codes, or a drop in engine performance — these are common signs that your exhaust cam gear sprocket may need replacement. The sprocket drives the exhaust camshaft, ensuring accurate valve timing and proper engine operation. A worn or damaged sprocket can cause mistimed valve events, poor performance, and potential engine damage. Replacing it with this genuine Subaru part restores accurate timing and protects your engine.

This is a factory‑original Subaru exhaust cam gear sprocket (OE part number 13049AA041), specifically designed for the right-hand (RH) side of EJ20/EJ25 turbo engines. It is precision‑machined to ensure accurate valve timing and optimal engine performance. The sprocket is a direct fit for the factory camshaft and requires no modifications. This is the same part sold at Subaru dealerships.
