Specifically designed for 2012–2020 Holden Colorado, Colorado 7, and Trailblazer models, Lid-Lock is a simple, no-nonsense fix for the common Colorado airbox mounting tab failure.

If your airbox tabs are cracked or broken, this restores proper clamping so the airbox can seal as intended, without needing to replace the entire unit.

Unlike other fixes, there’s no need to remove the airbox or disconnect your snorkel - just bolt it on and get back on the road. Built from a high-temperature, fibre-reinforced material, it’s designed to handle engine bay heat and vibration while restoring even clamping across the airbox lid.

Instead of replacing the entire airbox or relying on temporary fixes, Lid-Lock reinforces your existing factory airbox and fixes the part that actually fails.
