The PRL Cobra and PRL HVI are two of the most talked-about intakes for the 11th gen Civic 1.5T and 5th gen Acura Integra platforms. In this video I break down why I chose the Cobra for my 2024 Acura Integra A-Spec (DE4) instead of the PRL HVI.
Instead of just showing the part, this one explains the reasoning behind the choice and how it fits the overall build plan.

What This Video Covers
- Fitment & compatibility – Civic Si vs Integra DE4
- Design differences – true fender-well cold air (Cobra) vs high-volume airbox (HVI)
- Daily drivability & sound
- Performance potential (including PRL’s published dyno gains for the Cobra: up to +16 hp / +9 lb-ft on a stock Civic Si, no tune required)
- Future upgrade path – pairing with turbo inlet, ducts, etc.
- Price and value for a real-world street car
- Product and Tool Links
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.
