Joseph ★★★★★ Oct 21, 2026

My car idles so much smoother now since swapping in this set of eight injectors—the flow matching is dead-on across all cylinders. I noticed a nice bump in throttle response right away, especially during cold starts.

Natalie ★★★★★ Oct 20, 2026

These things fixed the stumble I had on my G8 when the weather turned cold. The flow rate is dead on and having the set matched makes all the difference for a smooth idle.

My '08 Vette LS3 felt a little lean at WOT after the cam swap, but these injectors dialed the fuel curve right in. The flow matching between all eight was spot-on out of the box, no dead times to chase.
