PRL Cobra Intake Sound | Before & After on Integra DE4 / Civic Si Platform

Want to know how the PRL Motorsports Cobra Cold Air Intake actually sounds in the real world? In this video I share a full before & after sound comparison on my 2024 Acura Integra A-Spec (DE4), which shares the 11th gen Civic Si (FL4) platform.

This post is for anyone trying to decide whether the sound and personality change are worth it before buying parts.

Why This Matters for the DE4 / Civic Si Platform

The Integra DE4 and 11th gen Civic Si share enough platform DNA that many performance parts cross over. The key is understanding fitment, sound, daily drivability, and whether the upgrade matches your goals.

Real-World Takeaway

This is less about chasing a single dyno number and more about how the car feels and sounds every day.
