440cc - 240/740/940 Red Block، BMW M3

Pulled the old injectors from my M3 and dropped these in—the idle smoothed out immediately, and the matched set took the guesswork out of balancing. Really solid upgrade for the price.

Swapped these into my '91 740 and the idle smoothed out immediately—the flow matching is clearly precise. Delivery feels consistent across the rev range, exactly what a Red Block needs for a mild turbo setup.

The spray pattern on these matched injectors is noticeably smoother than the worn ones I pulled out, and they dropped into the red block without any fuss. Car idles steady and pulls clean through the rev range now, exactly what I wanted for the 940.
