Customer Reviews (4.8 / 5 · 5 reviews)

Matthew ★★★★★ Oct 22, 2026

The matched set came with all 8 injectors sealed and ready, so no hunting for missing parts. Idle smoothed out immediately after swapping them into my E55, and the car pulls noticeably harder up top. Exactly what the supercharged 5.5 needed.

Stella ★★★★★ Oct 21, 2026

These injectors dropped right into my SL55 with no fuss, and the idle smoothed out immediately after swapping them in. The flow rate seems spot-on for the stock supercharged setup.

George ★★★★★ Oct 20, 2026

After fighting with a rough idle for months, this matched set of 8 went in over a weekend and the supercharged 5.5L pulls clean to redline every time. The flow match between each injector is spot-on, so no more cylinder-to-cylinder stumble when the boost hits.
