Bought this to have as a spare whilist I clean the original one in my wife's 2024 Honda Civic. Since it's a original K&N - took all of like 3mins to swap out the dirty filter ... snap this one in ... now I can clean & oil the original one which came with the K&N cold air kit & I'm good for another year before I swap 'em around again ...

Replacement for one that failed
I just rolled 120K on a civic and the filter I had was going through its 2nd 60K mile cleaning. I noticed that the pleats were shredded after de-greasing. This had multiple holes, Not sure how long the filter was failing, I will need to keep an eye on this one. Awaiting response from K&N about lifetime warranty. Wish me luck!

Es exacto las medidas
La verdad tenia duda si le fuera a quedar a mi carro dado a que el intake esta grande y este de 5 de diametro de la boca le queda perfecto. La verdad funciona como debe ser y funciona genial! Lo recomiendo ampliamente.
