PDF - 2022+ Honda Civic 1.5T High Volume Intake System Install Instructions
"Why didn't you design Cobra-style cold air intake like the 10th Gen?"
Unlike the 10th Gen Civic 1.5T chassis, the 11th Gen / 5th Gen Integra features a rather large and efficient air duct through the front bumper/grill from the factory. We elected to retain the factory air guides, and utilize them in our HVI design. Our engineers decided to take this one step further, though. In an effort to promote maximum airflow volume, our HVI comes standard with it's own injection molded High Volume Inlet Duct that attaches to the air box with OE-style clips and seals against the factory rubber seal/guide on the hood. We have also integrated a provision at the bottom of our air box for enthusiasts looking to turn this intake into a true cold air intake by installing our High Volume "Plus" Cold Air Intake Duct!

2025 Civic SI
"Awesome HVI!!! I love the sounds the turbo makes. Definitely turns heads."
2022 Honda Civic hatchback Sport Touring CVT
"Didnt know how it was gonna sound cuz all the vids i saw where for the SI but it didnt dissapoint u can definitely hear that "whoosh" sound. Easy to install . . . . please send me a free license plate cover :)"
Good starting point
"Install pretty straight forward but I do recommend watching a video. Shipped pretty fast and the packaging is top tier. If you looking for strictly turbo noises you will get a slight turbo noise with the radio volume all the way down. And if that’s all you’re looking for then it’s not worth the price tag. If you’re looking to upgrade your performance this is a good starting point. If i could go back id add 200 and got a KTurner first. Still a great product that i would have eventually purchase anyways but this wouldn’t have been my first purchase."
Great little mod
"I can feel the difference from stock and easy to install"
