William ★★★★★ Oct 22, 2026

The flow ratings on this matched set are dead-on straight out of the box, which saved me a trip to the dyno for balancing. Install was plug-and-play on my B20, and the car idles like stock even with the bigger feed.

Elizabeth ★★★★★ Oct 21, 2026

Had to upgrade my H22 for a turbo setup and these 550cc injectors plugged right in without any adapter hassle. The flow matching is spot on—idle is smooth and my wideband shows consistent AFRs across all four cylinders.

Kevin ★★★★★ Oct 20, 2026

Installed these on my B20 build and the flow matching was spot on out of the box—idle smoothed out instantly. Car pulls hard to redline with zero hesitation now.
