2400cc - WRX/Legacy GT/STI

Finally, my fuel trims are stable at high boost—the 2400cc flow rate handles E85 perfectly on my 2010 WRX. Installation was straightforward with the included o-rings, and idle quality is much better than I expected for such large injectors.

My old injectors couldn't keep up after the turbo upgrade, but these 2400cc units finally let me hit my target air-fuel ratios. They idle surprisingly well for such a massive flow rate, even on the stock ECU with a proper tune.

The install was pretty straightforward on my 2008 WRX, and the car idles much smoother than I expected for such large injectors. The flow rate is consistent across all four, which made tuning a lot less stressful.
