for basically a simple fabric sleeve that fits over the existing filter, it seems expensive. remains to be seen how it functions. the construction seems decent, and it was easy to install. the fabric must be very tricky stuff to warrant the price.

Great Product!

I have a carbon fiber hood on my car with vents in it so I needed something to cover up my K&N intake. I came across this item and was a little surprised that it was $30 but so far no water has been sucked in my intake and its rained almost every day here for the past month. I do recommend this product because it comes just as described and it works and fits perfectly!
