PRL Motorsports Cobra Cold Air Intake System – 2022–2025 Honda Civic Si 1.5T (11th Gen)

Overview

The PRL Motorsports Cobra Cold Air Intake System is designed specifically for the 2022–2025 Honda Civic Si 1.5T, delivering maximum airflow efficiency and a bold, aggressive induction sound. By drawing cool, dense air from the lower driver-side bumper duct, well away from the heat of the engine bay, this system helps lower intake air temperatures and maintain consistent power delivery. Built for both daily driving and performance testing, it provides reliable gains with the craftsmanship and quality PRL is known for.

Proven Performance Gains

Independent dyno testing on a stock Civic Si (no tuning required) confirms the Cobra Intake’s ability to improve throttle response and horsepower throughout the powerband. Results showed:

• +16 horsepower
• +9 lb-ft torque
• Gains sustained across much of the RPM range
• Noticeable peak improvements at key points in the curve

(Dyno chart reference: Yellow = Cobra Intake, Green = OEM airbox.)
