850cc - Evo X 4B11T

Swapped these in over the weekend and the idle smoothed right out with zero hiccups, even before I flashed a new tune. The fact that they came as a matched set of four saved me the headache of chasing individual flow rates.

The flow matched perfectly with my stock fuel rail, no adapters needed. Idle smoothed out nicely after the install, and my tuner said the dead times were spot-on across all four injectors.

Bolted these in on my 2009 Evo X and the car idled smoothly right away—no fussing with individual injector flow tuning. The matched set really makes a difference for consistent fuel delivery across all four cylinders.
