550cc - 240sx SOHC KA24E

Installed these 550cc injectors and the improvement in throttle response was immediate. The matched set of four made tuning my KA24E much smoother than my old mismatched ones.

Installed these on my 89 240sx and the car is finally running the way it should. The matched set meant no fiddling with different flow rates, and the 550cc rating works perfectly with my current setup.

The 550cc flow rating was spot-on for my lightly modified KA, and the matched set saved me the hassle of chasing uneven idle issues. Installation was straightforward, and I finally feel confident in the fuel system.
