SPOOL Port Injection Plug and Play Harness Kit – R8/Huracan V10

SPOOL Port Injection Harness Kit – R8/Huracan

It’s no secret that our V10s are expensive engines, and protecting that investment with high-quality components is always a priority. When installing aftermarket fuel injectors in your port injection fuel rails, installers often have to rely on plug-and-play adapters to convert the OEM injector connectors to USCAR/EV14 or Bosch EV1 connectors in order to run injectors such as Injector Dynamics or Bosch units. Unfortunately, using these adapters adds additional connection points—up to ten more potential failure points in the system.

The Spool Performance Port Injection Harness Kit eliminates that problem entirely. This kit replaces both of your OEM secondary port injection harnesses with brand-new harnesses that plug directly into your factory wiring and terminate with EV14 (USCAR) connectors. That means no plug-and-play adapters and no cutting or crimping new terminals onto your already short factory injection harnesses. Our harness also labels each cylinder number so there’s no mixing up or guessing which connector goes where. 

The result is a cleaner installation, improved reliability, and peace of mind knowing your fuel system wiring is built properly from the start.

Not all wiring is created equal. Our harnesses are built using motorsport-grade Tefzel wire, commonly used in professional racing and aerospace applications for its exceptional durability and resistance to heat, chemicals, and abrasion. We also use high-temperature heat shrink rated for 130°C (260°F) to ensure long-term reliability in harsh engine bay environments.

This harness is compatible only with EV14 (USCAR) style injectors, such as Injector Dynamics injectors used on Lamborghini Huracán / Audi R8 V10 applications.

Injector Dynamics injectors can also be purchased directly through us. For pricing and availability, please contact sales@spoolperformance.us
