650cc - Honda S2000 F20C

The fuel rail adapters made installation straightforward and the flow-matched data sheet gave me confidence in the setup. Idle quality actually improved over my old 440cc injectors, which was a nice surprise.

Installed these in my S2000 last weekend and the idle is noticeably smoother than with the old injectors. The consistent fuel flow at WOT gives me real confidence in the tune.

The machining on these injectors is clean and the O-rings fit snugly into the rail without needing any extra persuasion. My idle smoothed out immediately after swapping them in, which is exactly what I was hoping for.
