Description
The Mishimoto MMAI-RGR-PLG is a purpose-built intake duct plug for the 2019-2023 Ford Ranger 2.3L EcoBoost, designed to work hand-in-hand with the Mishimoto Performance Air Intake and Borne Off-Road Snorkel. Where the Ranger’s factory duct pulls fresh, cool air from the grille for everyday street driving, this small but essential accessory seals that duct off the moment you head onto the trail, ensuring the truck breathes only through the snorkel.
Owners weighing a Mishimoto cold air intake against other cold air intakes on the market, whether it’s a k&n cold air intake, an afe cold air intake, or another cold air induction setup, will find that few systems offer this kind of trail-ready flexibility. This intake plug protects the air intake filter and the broader air intake system from dust, debris, and water intrusion by shutting off the street-side duct entirely, so the intake filter and intake tract stay clean when conditions get rough. Because it snaps securely into place without tools, switching between snorkel-only off-road airflow and open-duct street driving takes only seconds, keeping your Ranger’s air intake filter and cold air intake filter protected exactly when it matters most.

It is designed specifically for Rangers equipped with the 2.3L EcoBoost engine on the T6 chassis, matching the same applications covered by the Mishimoto Performance Air Intake and Borne Off-Road Snorkel for this platform.
