I have a 2020 Civic Si. Almost on day one I installed PRL Motorsports Stage 1 Intake. I liked it as it smoothed out the acceleration and improved gas mileage. I finally decided to get your cold air intake. I waited to install it on the day I changed the oil and rotated the tires, as I wanted access to the underside of the car. Installation was straightforward. No real problems, even for this 78 year old. Performance improved. Much more linear acceleration. Just drove 600 miles to my daughter’s house and everything just felt “ right”… the way it should have been from the factory. Great product, good price. Impressed!
The way this intake sounds with the metal body is unmatched. My car is tuned with ktuner for 21 psi. With anti-lag set at 3800 rpm and higher I lose even less boost after installing this intake.
This will make your civic sound amazing. It is very easy to install, I've done it at home with no problems.
100% would recomend it.
By far the best intake for the 10th gen civic si. Highly recommend!
great. amazing sounds. easy install. well worth it.
