Upgrade your 2004 - 2005 Honda S2000 with the AEM 21 - 514R Performance Cold Air Intake System. This system boosts horsepower and torque by replacing the restrictive factory air filter and housing. It's custom - designed, tuned, and dyno - tested for your specific Honda S2000 model. The oversized AEM Dryflow synthetic washable air filter ensures great air flow, filtration, and performance. Located in the driver - side wheel well, it reduces intake air temperature, further increasing power. The mandrel - bent aluminum intake tubing has a durable red powder - coated finish. It's compatible with the engine's factory emissions control devices, including replacement breather and vacuum hoses. The oil - free, synthetic AEM Dryflow air filter can last up to 100,000 miles before cleaning (depending on driving conditions). Backed by AEM's Lifetime Limited Warranty. Note that some AEM air intakes may not be legal in California and other states with similar emission standards. Check the 21 - 514R vehicle applications for each vehicle's legal status.

Using this AEM cold air intake is easy. First, remove your vehicle's old air filter and intake housing. Then, install the new intake system in its place, making sure all parts are securely connected. For maintenance, check the air filter regularly. You can wash the AEM Dryflow filter when it gets dirty, but make sure it's completely dry before reinstalling. When it comes to legal issues, always check your local emission regulations before installing. This system is designed to work with your vehicle's factory emissions control devices, but some areas may have restrictions. Enjoy the increased horsepower and torque this intake provides, and remember to follow all safety procedures during installation and use.
