1100cc - BMW M5 E39 S62, M3 E90/E92/E93 4.0L S65

Finally got these installed in my M5 E39, and the 1100cc flow rate made a noticeable difference in throttle response under hard acceleration. The set matched perfectly out of the box with no adjustments needed.

Swapped these into my M3 E90 and the idle smoothed out immediately compared to the old set. The 1100cc flow is plenty for my supercharged setup.

The flow-matched set meant zero fuss on install—each one clicked in and idled smooth from the first start. My E39 M5 pulls cleanly to redline now, no more hesitation in the mid-range. Downpipes and a tune are next, but these 1100cc injectors have plenty of headroom.
