AEM Induction Cold Air Intake System

For 2008-2012 Honda Accord 2.4L 4-Cylinder (Part # 21-822C)

Product Description

Unlock the true potential of your 8th-Gen Honda Accord with the AEM Performance Cold Air Intake System (21-822C). Designed, tuned, and dyno-tested specifically for the 2.4L engine, this system replaces your restrictive factory air filter and intake housing to deliver noticeable horsepower and torque gains—estimated at an impressive +11 HP @ 3200 RPM.

Air enters the system through an oversized, oil-free AEM Dryflow synthetic air filter. To ensure the coldest, most dense air charge possible, the filter is strategically relocated to the driver-side wheel well. The intake tubing itself is constructed from smooth, mandrel-bent aluminum and finished in a durable, show-quality Gunmetal Gray powder coat.

⚠️ IMPORTANT FITMENT NOTE:

Vehicle Fitment: Fits 2008, 2009, 2010, 2011, and 2012 Honda Accord equipped with the 2.4L 4-Cylinder engine.
Trim Compatibility: Fits EX, EX-L, LX, LX-P, LX-S, and SE trims.

Note: This system seamlessly accommodates the engine's factory emissions control devices, including the mass air flow (MAF) sensor and crankcase vent tube.
