Honda Civic Si Fuel Injector Adapter - Grams Performance - Plug and Play - `12-`13. This Grams Performance adapter provides a direct, plug-and-play connection to fit Grams 550cc, 750cc, and 1000cc EV6-style injectors to the 2012–2013 Civic Si factory harness.

Designed for enthusiasts who are upgrading injectors without cutting or splicing the factory wiring, this adapter converts EV6-style injector pins to the Honda connector for an easier install. Each adapter is sold individually and requires no soldering or additional wiring—simply plug the injector into the adapter and the adapter into the factory harness.
