Sebastian O. ★★★★★

Had to bump up my idle fuel pressure a bit to get them dialed in on my K20, but once that was sorted the car runs noticeably smoother through the entire rev range. Definitely worth the swap for anyone pushing more power.

Adam N. ★★★★★

Plugged these into my SRT-4 and the car pulls harder through the mid-range without any hiccups. The matched set made tuning a breeze with no flow differences between injectors.

David ★★★★★

Swapped these into my K20 and the idle smoothed right out after a quick relearn, the matched set made tuning way less guesswork. Dead-on 550cc flow across all four, no dead spots in the midrange.
