The filters saved me money on gas, and it was very easy to install. I wil buy K&N again.

I can't say I noticed an increase in my horsepower or MPG since installing the filter. But I do know that I won't have to buy another air filter again since it's cleanable and reusable... it's also an oil-free filter so you won't have to worry about oil getting onto the MAF...
