Product Description

The Injen SP1686BLK Black SP Cold Air Intake is a performance-oriented intake system engineered specifically for the 2013-2017 Honda Accord equipped with the 3.5 L V6 engine. As part of Injen's flagship SP Series, this cold air intake replaces the restrictive stock air path with smooth mandrel-bent 6061-T6 aluminum tubing and uses patented MegaRam (MR) and Air Fusion technologies to optimize airflow while maintaining safe air-fuel ratios without requiring additional ECU tuning. The included SuperNano-Web dry air filter increases filtration surface area for better breathing and is fully serviceable for long-term maintenance.

Dyno-proven gains of up to approximately 8 hp and 7 lb-ft of torque over the stock intake help deliver improved throttle response and acceleration, along with a more engaging induction sound under throttle. The black finish enhances the engine bay's aesthetics while the system remains backed by Injen's limited lifetime warranty. Please note this intake is not currently CARB exempt and is restricted in states with strict emissions regulations.
