Decapped Fuel Injectors - High Flow Fuel Injectors

Q: How much horsepower will 80lb/hr injectors handle?

700+ HP: 80 lb/hr will usually be enough for most builds up to about 700-800hp. These are rough estimates. We recommend confirming injector sizing with your tuner.

Performance High Flow Fuel Injectors for LS Engines

Our decapped LS fuel injectors are professionally modified and flow-matched for high-performance applications. Each set is fully rebuilt and includes brand new o-rings for a leak-free install.

These injectors support both standard pump fuel and E85, making them ideal for turbocharged, supercharged, nitrous, and other racing setups. Precision flow matching minimizes cylinder-to-cylinder fueling differences, improving power delivery and consistency under load.

You’ll find plenty of DIY decapping guides on YouTube, but we bring years of hands-on experience, advanced equipment, and testing that DIY methods can’t match. Our injectors are matched within tight tolerances to reduce risks of lean or rich conditions and help balance cylinder pressure.

Compatibility

Our decapped injectors are compatible with a wide range of GM LS platforms, including:

LS1, LS3, LS7
LSA, LS9
L76, L92, L98, L99, LM7

Why Choose Decapped Injectors?

These injectors offer significantly higher flow rates than OEM units, making them ideal for LS swaps, turbo, supercharger, nitrous, or race-ready builds. Whether you're running pump gas or E85, these injectors can handle the demand.

Do Bigger Injectors Increase Horsepower?

While injectors alone don't increase horsepower, having the correct-sized high-flow injectors is critical for fueling upgraded engines. Our flow-matched sets ensure each cylinder receives the right amount of fuel, improving tuning precision and reliability.

Will Bigger Injectors Hurt MPG and performance?

If you throw them into a stock or near stock motor, yes absolutely. However these high horsepower builds require way more fuel than stock injectors can deliver. When properly tuned, high-flow injectors deliver exactly how much fuel your engine needs, usually it's a lot of it. Our precision-matched sets help reduce rich or lean conditions in each cylinder that could otherwise waste fuel.

What Makes Our Decapped Injectors Better?

Unlike DIY decapping methods found on YouTube, we use professional equipment to flow-match injectors within tight tolerances. This ensures even fuel distribution, reduces knock potential, and improves power consistency between cylinders.

Installation Notes

Some vehicles may require adjustment to fuel rail height. Please verify fitment for your specific setup. Our team is available to assist with technical questions.
