Customer Reviews (4.6 / 5 · 5 reviews)

William ★★★★★ Oct 21, 2026

The packaging was surprisingly sturdy, and the casting quality around the valve seats looks flawless. Bolted on without any modifications needed.

John ★★★★★ Oct 20, 2026

The cylinder head bolted right up to my FK8 with zero fitment issues, which was a relief since I was worried about compatibility with the international model. The casting looks clean and all the bolt holes lined up perfectly, so the install took less than an afternoon.

Julian ★★★★★ Oct 19, 2026

Had a small oil leak from the original head after a track day, and this factory replacement fit perfectly with no issues at all. The part number matched exactly, and the machining on the mating surface looks flawless.
