DeatschWerks 450cc Injectors – Honda Acura B/D/F/H-Series – Set of 4

Upgrade your Honda or Acura fuel system with the DeatschWerks 18U-04-0450-4 injector set. This matched set of 4 injectors is designed for compatible Honda / Acura B-Series, D-Series, F-Series, and H-Series applications and is commonly used for performance, turbo, engine swap, and tuning setups that require more fuel flow than factory injectors.

This injector set is marketed as a 450cc set, while DeatschWerks’ listed specification shows a 440 cc/min flow rate. The injectors use a USCAR connector shape and are supplied as a matched 4-cylinder set for consistent fuel delivery across all cylinders.

These injectors are intended for modified setups that have proper ECU tuning and supporting fuel system components. They should not be installed on a stock tune.
