PRL's Cobra Cold Air Intake System for the 2022-2025 Honda Civic Si 1.5T is a complete cold air solution engineered to bring maximum performance and clean, aggressive induction sound to your 1.5L turbocharged platform. This system pulls fresh, dense air from the lower driver side fender well—well outside the engine bay—to promote cooler IATs and more consistent power delivery.
Engineered for both performance testing and everyday drivability, this intake system delivers dependable gains with the same proven quality behind every PRL product.
Dyno testing confirms that even without a tune, this system brings measurable improvements in power, response, and sound. Tested on a completely stock Civic Si without tuning, our Cobra intake delivered up to:
+16 horsepower
+9 lb-ft of torque
Gains sustained throughout much of the RPM range
Peak improvements measured at key points in the powerband
Test results from dyno runs on a stock Civic Si (no tune).
