This is a nice product, k&n know what they’re doing when it comes to quality products. But I’m not gonna lie, I had a hard time installing this. The instructions weren’t very clear on what pieces of hardware to use from the supplied hardware in the kit and the pictures aren’t much of a help either. Great product, looks good and sounds good, but I would install with someone who knows what they’re doing and make sure you have a lot of daylight or good lighting
