Review on 🔧 K&N Engine Air Filter: High Performance, Premium, Washable Replacement Filter for 2012-2019 Honda/Acura/Kia/Hyundai (Civic Si, ILX, NSX, K4, Mistra) by Kevin Parker

fits my 2012 Honda Civic Si Sedan perfectly. I hear a slight growl and a much more pleasant roar as the engine revs up, but as far as horsepower goes, I can guarantee you it won't go above 1 or 2hp. The main reason I bought it was that it can be reused, it can be washed. Love it, I no longer have to buy paper filters every time. I have had K&N filters on all my cars and I can say they are truly amazing. I also have a 2005 Acura RSX Type-S and a K&N Typhoon SRI and I love them. it's a much louder roar and ummmfh at that. I'd say that gives you about 10 horsepower, but it will come at the same time before I switch to a K&N induction system.
