Customer Reviews (5.0 / 5 · 5 reviews)

Natalie ★★★★★

Dropped these into my LS build and the engine idles way smoother than with the old stock injectors. The consistent fuel delivery from the matched set really shines on cold starts.

Carter E. ★★★★★

The flow-matching on these injectors made tuning a breeze—no more chasing lean cylinders. Idle is dead smooth and the car pulls hard all the way to redline. Honestly, for the price, you can't beat the consistency.

Adam ★★★★★

Swapped these into my LS swap and the idle smoothed out immediately—the flow-matching is clearly doing its thing. They bolted right up to the stock rails with no adapters needed, and the car pulls hard all the way to redline.
