Very nice very very nice
Style: CA10467
Honestly I didn’t use it yet but just by inspection it. Looks very good. On thing I have to say is. Amazon did it again. Perfect. The outside box was a little dented and slightly crushed on the corner but the inside box that holds the air filter was perfect. Me being a delivery driver at one time am amazed that the packages always come delivered in perfect condition. I know how easy they can get damaged. Great job Amazon and the drivers and the whse and package dept. great job Update, I just put the air filter in my Honda and it feels faster and more responsive. I will be buying this air filter again. I bought a spearhead air filter for my tundra , and it’s a good filter but I think I am going to switch to a kax filter for two reasons First I said I put it in my Honda and it feels faster and responds quicker. Second. I know it’s not a good reason but I like the color. But I really feel the difference.
