Injectors grouped by measured flow for high-horsepower builds.

We service port fuel injectors. Have direct-injection (GDI) injectors? Email us before you ship so we can tell you what we can test. Rush service is +$75. If an injector fails testing after cleaning, we tell you and recommend replacing it, instead of sending it back as good.

Questions

Before you ship

How should I pack injectors?

Bag them, cushion them in a small padded box so they can't rattle, and keep the plastic caps or tips protected. Put your job number on a note inside. Don't send the fuel rail unless we ask for it.

Can you clean a single bad injector?

Yes, at $25 each with a two-injector minimum. Sending the whole set lets us balance them against each other, though, which is usually what fixes the misfire or lean cylinder.

Do you sell new or matched injectors?

Not online yet. Email us about a flow-matched set for your build.
