Genuine GM Holden RG Colorado Air Box Lid 52100555

Factory replacement Genuine GM air box lid, part 52100555. This upper section of the intake housing secures the air filter element and houses the mass air flow (MAF) sensor, ensuring correct airflow into the engine.

Common Issue:
- Over time, the factory lid can distort from heat and stress, preventing even pressure across the air filter seal. This can allow dust or unmetered air to bypass the filter. Replacing the lid ensures correct sealing and reliable airflow.

Fitment:
- Holden Colorado RG (2012–2020) – all engine variants
- OEM direct replacement for the factory air box lid
