BMW S58 포트 인젝션 연료 레일 w/ 배관 키트

The fuel rail itself is CNC-machined and the included stainless braided lines made routing the secondary injectors straightforward. Paired with the factory manifold, my M4’s fueling feels rock-solid at higher boost.

Mounted this on the S58 and the kit lined up perfectly with the factory manifold, no fighting or bending needed. The braided lines and fittings feel solid, and the whole setup went in clean in an afternoon.

I was pleasantly surprised how well this kit mates to the factory manifold on my M3 — everything lined up perfectly with no modifications needed. The plumbing kit saved me hours of piecing together fittings.
