Description
Upgrade your 2017-2020 Honda Civic Si with the Mishimoto Performance Air Intake Kit, designed to deliver noticeable improvements in engine airflow and throttle response. This direct-fit modification enhances your turbocharged Civic’s performance while adding an aggressive under-the-hood sound during acceleration and boost. Crafted with precision in the USA, the intake features a venturi-style MAF housing that brings in smoother airflow compared to traditional designs, contributing to more efficient combustion and power gains. The silicone intake arm reinforced with steel wire ensures durability and optimal airflow management, while the black-powdercoated steel airbox shields the high-performance Mishimoto air filter from engine bay heat and prevents hydrolock by positioning closer to the hood for better protection and airflow control. The use of the stock air diverter ensures seamless integration with the existing intake system, making this a straightforward bolt-on upgrade. Tested on the dyno, this intake consistently produces up to 4 horsepower and 4 ft-lbs of torque gains on the stock tune, providing a significant performance boost without the need for tuning adjustments. The Mishimoto intake is fully compliant with EPA standards and includes the Mishimoto Lifetime Warranty, reflecting the high quality and craftsmanship behind this product. This intake is an ideal choice for enthusiasts seeking to improve their Civic Si’s airflow and sound while maintaining a reliable, easy-to-install upgrade.
