Fuel Injectors Matched Set 440cc (42lb)

The Fuel Injectors Matched Set 440cc (42lb) by Deatschwerks is purpose-built for serious engine builders and high-performance enthusiasts seeking reliable fuel delivery on turbocharged and naturally aspirated platforms. This eight-injector set delivers precise atomization at 42 pounds per hour, making it ideal for mild to moderately boosted applications where OEM injectors fall short. Whether you're upgrading a tuned four-cylinder or balancing fuel curves across a V8 platform, matched injectors eliminate lean-running risks and cylinder-to-cylinder imbalances that plague mismatched fuel systems.

Each injector in this matched set features the proven Bosch EV14 design—a motorsports-grade pintle that ensures consistent spray patterns and minimal dead time variation across all eight units. The USCAR connector configuration provides universal fitment across countless platforms without requiring expensive adapters, while the 440cc flow rate offers a sweet spot for engines running modest boost levels or naturally aspirated combinations pushing 400–500 horsepower. Deatschwerks' meticulous flow-matching tolerances (typically within 1–2% across the set) prevent the cylinder imbalances that cause rough idle, hesitation, and tuning headaches that plague budget alternatives.

Mechanics and tuners commonly specify this fuel injector set for forced-induction builds, ECU tune-ups, and fuel system upgrades where factory injectors are electronically or physically inadequate. Installation requires removing the fuel rail, but no fuel system modifications are necessary on vehicles already fitted with USCAR-style connectors—a massive advantage for bolt-on performance. Always flow-test matched sets post-installation and verify that your fuel pump can sustain the aggregate 336 cc/min demand at full load to avoid lean-out conditions and detonation risk.
