Description
Enhance your 2006-2011 Honda Civic Si with the Mishimoto Performance Air Intake, designed to deliver increased horsepower and a more aggressive engine tone. This complete kit replaces the restrictive stock airbox, utilizing a mandrel-bent aluminum intake pipe available in polished or wrinkle black finish for a sleek look. The CNC-machined MAF housing ensures precise airflow readings, resulting in a smooth power band and reliable performance. A dedicated heat shield reduces heat soak by blocking hot air from the exhaust manifold, helping to maintain optimal intake temperatures for consistent power gains. The Mishimoto air filter offers 85% more surface area than stock filters, providing superior airflow while capturing dirt and debris effectively. Fully serviceable, the filter ensures long-term durability and dependable filtration. Installation is straightforward, taking less than an hour with included clamps, silicone couplers, and hardware, and it works seamlessly with the factory tune. The intake produces a notable increase of up to 8 wheel horsepower and 6 foot-pounds of torque, verified through dyno testing, making it an excellent upgrade for street driving or autocross enthusiasts. The kit also delivers an unmistakably aggressive intake sound, especially when VTEC activates, enhancing the driving experience. Designed and manufactured in the USA with the Mishimoto Lifetime Warranty, this performance intake offers a reliable, bolt-on upgrade that improves both power and sound without requiring ECU tuning. Whether you seek more performance or a richer engine tone, the Mishimoto Civic Si Intake is a proven choice for Honda enthusiasts seeking quality and performance.
