Upgrade your Honda Civic Si (2017-2020) with the Injen EVO1501 Evolution Cold Air Intake, engineered to deliver increased performance and a sporty underhood appearance. This system features a durable roto-molded polyethylene tube and housing, designed to withstand harsh engine bay conditions while providing optimal airflow. The included SuperNano-Web dry air filter is fully serviceable, offering long-term filtering efficiency and easy inspection through the Injen clear-view badge. The filter's design maximizes air volume intake, contributing to significant horsepower and torque gains, making it a popular choice among enthusiasts seeking reliable performance enhancements.
Installation is simplified with Injen’s Twist-Lock technology, which securely integrates the air filter to the housing using fewer parts and tools. This design results in one of the quickest and most straightforward setups available on the market, with a perfect OE fit and aggressive underhood aesthetics. Reinforced automotive-grade silicone couplers ensure a tight seal, preventing leaks and maintaining optimal airflow. The stainless steel band clamps with inner protective liners further contribute to the system's durability and reliability. Dyno testing has confirmed performance gains of up to 13 horsepower and 12 lb-ft of torque, with some setups reaching as high as 22 hp and 18 lb-ft, demonstrating the system's proven efficacy.
This intake system is designed to work with the stock calibration of your vehicle, preserving factory drivability while maximizing power. The aggressive intake growl under acceleration enhances the driving experience without sacrificing quality or reliability. Please note that this product is not CARB exempt and is not legal for use in California or on California-registered vehicles. Backed by Injen’s limited lifetime warranty and proudly made in Pomona, California, the EVO1501 is a reliable upgrade to elevate your Civic Si’s performance and appearance.
