Show original supplier description
The AEM 21-405C Performance Cold Air Intake System is engineered to significantly improve your vehicle's airflow, leading to measurable horsepower and torque gains. By replacing the restrictive factory air filter and intake housing, this system allows your engine to breathe more freely. It is specifically designed, tuned, and dyno-tested to fit 1992-1996 Honda Prelude models, ensuring a precise fit and optimal performance. The core of the system is the oversized AEM Dryflow air filter, constructed from an oil-free synthetic media. This filter provides excellent airflow and filtration and can last up to 100,000 miles before requiring cleaning, depending on driving conditions. The intake tubing is crafted from mandrel-bent aluminum and finished with a durable gunmetal gray powder coat. The intake air filter is strategically relocated to the passenger-side wheel well. This placement is intended to draw in cooler ambient air, thereby reducing intake air temperature and further increasing horsepower. This cold air induction system is backed by AEM's Lifetime Limited Warranty. Note that some AEM air intakes may not be legal for sale or use in California and other states with similar emissions standards; always verify the legal status for your specific vehicle application.
