G20/SR20/240sx SR20DET/KA24DE -550cc

Running these 550cc injectors on my SR20DET cleaned up the idle and throttle response compared to the worn stock ones. The matched set made tuning straightforward since all four flowed the same from the box.

Dropped these into my KA24DE and the idle smoothed right out—the 550cc flow is exactly what I needed for my mild turbo setup. They bolted right up to the stock rail without any adapters.

My SR20DET was running lean with the stock injectors, but these 550cc side feeds got the fuel pressure dialed in perfectly for my turbo setup. The matched set made installation straightforward since I didn't have to flow-test each one individually.
