Plug-and-Play Integration
-
Harness Adapters Included: Comes with the necessary wire adapter harnesses to bridge your Subaru's factory clips to the high-performance Bosch USCAR connector.
-
Flow Matched: Every set is dynamically matched within 1% to ensure cylinder-to-cylinder consistency, which is critical at these high flow rates to prevent lean conditions.
-
Stainless Internals: Designed to handle the high pressures and diverse fuel types required by professional tuners.
⚠️ IMPORTANT: E85 USE & MAINTENANCE WARNING
Due to the tight internal tolerances of the 2200cc high-flow internals, these injectors require specific maintenance when used with E85/Ethanol fuels.
DO NOT allow E85 to sit in these injectors for extended periods of inactivity (longer than 2-3 weeks).
If the vehicle will be stored, we strictly recommend flushing the fuel system with regular pump gas to prevent "gumming" or sticking of the internal needle. Failure to follow this maintenance may lead to injector clogs or stuck pintles.
