Upgrade your 2016 - 2021 Honda Civic (excluding Type R models) with the AEM 21 - 792C Performance Cold Air Intake System. It boosts horsepower and torque by replacing the restrictive factory air filter and intake housing. Designed, tuned, and dyno - tested for specific Civic models, it features an oversized AEM Dryflow synthetic washable air filter. This filter provides excellent air flow, filtration, and performance. Placed in the original air box space, it's shielded by a heat shield that lowers intake air temperature and increases power. The mandrel - bent aluminum intake tube has a durable gunmetal gray powder - coated finish. It's compatible with the engine's factory emissions control devices. The oil - free, synthetic AEM Dryflow air filter can go up to 100,000 miles before cleaning (depending on driving). Easy to install with common tools and backed by AEM's Lifetime Limited Warranty. Note that some intakes aren't legal in California and similar states, while others are 50 - state legal. Check the 21 - 792C vehicle applications for legal status. Fits 2016 - 2020 EX, 2016 - 2021 LX, 2016 - 2018 LX - P, 2019 - 2021 Sport, and excludes 2017 Type R models.

Using your AEM Cold Air Intake is simple. First, gather commonly available tools and follow the included instructions to install it on your compatible Honda Civic. During use, keep in mind that some models may not be legal in California and other states with similar emission standards, so check the legal status for your vehicle. For maintenance, the AEM Dryflow air filter can last up to 100,000 miles before needing cleaning, but this depends on your driving conditions. When it's time to clean, follow the cleaning instructions provided. Regularly inspect the intake tube and heat shield for any signs of damage or wear. If you have any issues, refer to AEM's Lifetime Limited Warranty for support.
