Customer Reviews (4.4 / 5 · 5 reviews)

Mia E. ★★★★★

The 550cc injectors dropped right into my Z4 and the car pulls much stronger through the mid-range now. Idle smoothed out after the first few miles and fuel trims look perfect.

Brian D. ★★★★★

After swapping out my old injectors in the '03 M3, the 550cc set cured a rough idle I'd been chasing for months. Idle is now perfectly smooth, and the engine pulls noticeably harder to redline. The matched set concept really paid off, as all six fuel trims settled within 2% of each other.

Matthew H. ★★★★★

Dropped these into my Z4 and the car idles smoother than it ever has with the old injectors. The 550cc flow rate feels perfect for my bolt-on setup.
