E85 COMPATABLE

Feed your truck-based LS build with injector control built to handle real power.

When horsepower climbs, weak fuel delivery turns into a problem fast. The HPI Injectors Set of 8 LQ4 / LQ9 / 4.8 / 5.3 / 6.0 Delphi Shorty Multec High Impedance Fuel Injectors is built for performance combinations that need fast response, dependable fueling, and consistent cylinder-to-cylinder control under load.

BUILT FOR TRUCK LS PERFORMANCE

At HPI Injectors, these high-impedance shorty injectors are built for LQ4, LQ9, 4.8L, 5.3L, and 6.0L applications that use the Delphi / Multec style format. The live page describes them as being based on Bosch EV6 fuel injector technology and designed from Bosch core architecture, giving your build the response and linearity needed for strong street, boost, ethanol, and race performance.

MATCHED FOR CONSISTENCY

Each set is listed as matched within 1% static flow and 2% dynamic flow, helping improve cylinder-to-cylinder consistency across the set. That means cleaner fueling, smoother operation, and better repeatability when the tune matters.

E85 READY. BOOST READY. BUILT TO LAST.

These injectors are described as using stainless steel internal parts and a custom HPI tip with an added screen to help increase injector life. The page also states they are E85 compatible, compatible with ethanol and methanol, and capable of operating with up to 9 bar of fuel pressure differential.

DESIGNED TO TUNE CLEAN

Injector dead times and flow ratings are provided to help make fuel map calibration easier. The live page also emphasizes strong idle quality, drivability, and smoothness, making these injectors a strong option for high-performance builds that still need clean manners on the street.

WHY HPI INJECTORS

At HPI Injectors, fueling is not an afterthought. These injectors are built for enthusiasts who need control, consistency, and confidence when the engine is under pressure. From street-driven truck LS builds to serious boosted combinations, this set is designed to deliver the fuel your combination needs when it matters most.
