Amelia ★★★★★ Oct 22, 2026

I swapped the stock injectors in my '01 Camaro SS for these 550cc units and the idle smoothed out noticeably. They're a matched set of 8, so no need to mess with flow rates.

William ★★★★★ Oct 21, 2026

Plugged these into my '04 Mustang GT and the idle smoothed right out – no more stumbling at stoplights. The flow rate feels perfect for my bolt-on setup, and the set was matched within 1% out of the box.

Olivia ★★★★★ Oct 20, 2026

Took my SVT Lightning’s old rails off and these 8 matched units dropped right in without any flow surprises. Idle smoothed out nicely and the 550cc rating matches what the listing promised for the modular motor.
