The OEM GT500 CAI that comes with the Phase III kits has a “muffler” in it which cuts down on blower noise so Ford could pass noise emissions standards. And that’s no fun, right? This kit replaces the OEM CAI and has no “muffler” so it lets out all of that glorious blower scream. The OEM CAI is 100mm so this replacement bumps you another 20mm.

Features:

-Full CAI. You would not be using any of the OEM one.

-120mm diameter for more efficient airflow to the blower.

-120mm diameter also allows more blower noise out than the standard 100mm OEM unit with the “muffler”.

-120mm will support up to 800rwhp

-Comes with washable air filter
