Even some diehard gearheads don’t give much thought to fuel injectors. They plug ’em in and, as long as the engine runs, that’s the end of the story.

Yet you really should be mindful of your fuel injectors—because they are NOT all created equal, especially in high performance applications.

In fact, when tested in a real-world environment, a fuel injector may be listed as an OEM-spec replacement or have a prescribed flow rate that’s far different than what’s printed on the box.

And that’s precisely what the fuel injector experts at Excess Injectors found out when they did a side-by-side comparison test between some popular fuel injectors.

An improperly spec’d fuel injector can result in a poorly running engine. Worse yet, you risk running into a too-lean situation that may lead to detonation and catastrophic engine failure.

Excess Injectors has been in the high performance EFI game for dang-near 50 years, so its folks know an awful lot about feeding a thirsty motor. And over those decades they’ve tested a massive range of fuel injectors for consistency, reliability, and overall performance.

So, in this short video, you’ll see a solid comparison between different injectors that supposedly share similar flow rate specs—suffice it to say, you’ll see a difference here.
