Review on 🚀 Maximize Honda Civic Si's Power with K&N Cold Air Intake Kit (2017-2019) - Boost Horsepower and Performance - 69-1504TR by Mike Quade

Don't expect horsepower gains, just change the power curve. But it will be a good helper mod for the things to come. Basically just gives you that satisfying tubro sound. You can clearly hear whether the windows/sunroof are closed or not. If you listen to music on volume 18 when everything is closed, you won't hear it. Looks good under the hood. My only complaint is with the removal of the factory airbox rather than the product itself. Grabbing the top half of the airbox is easy. However, removing the floor is a major pain. You don't have to remove the bottom half to install a new air intake, but I didn't want a random half-loose piece of plastic just sitting there collecting engine debris in the engine bay. To do this you have to go under the car and remove the metal skid plate, easy but there is a 10mm screw which is almost impossible to reach. I used a hand wrench because that was all I could get my hands on. I don't know how you would reinstall it without removing the case from the frame.
