Spec-C intake manifold — complete

Complete original C-spec intake manifold including throttle body, wiring harness, sensors and vacuum lines.

No injectors included.

Why people look for this version:

✔️ Sharper throttle response than WRX manifold
✔️ Better airflow layout under load
✔️ Cleaner OEM performance base
✔️ Rare complete setup with loom included

Compared to WRX:
WRX manifolds are built more for daily drivability. This C-spec version gives a more direct response and feels noticeably more aggressive in tuned setups.

Compared to standard STI:
STI is already strong, but C-spec stays desirable because of its rarer configuration, flow characteristics and complete OEM package.

Especially interesting for serious EJ builds, swaps or anyone wanting proper OEM+ performance.
