I've had my Civic Si for two years and decided it was time add a little more hp and help with acceleration. 45 minutes of easy install. Definitely meets my expectations. Adds a nice growl to the little 4 cylinder as well. Very happy.
Quality and fitment are great. However there is very minimal gains under daily daily driving conditions. Intake sounds great and I can hear more turbo sound.
This intake is reasonable for the price i paid for. Alot of others say these are not good but i personally seen a gain in horsepower and sound. Of course i also bought the water cover to go on the filter as well to avoid water getting on the filter i reccomend for any one using a cold air intake.
