K&N filters

Help in what way? They generally don't filter as well as a paper filter, but do add a couple of HP. They are also washable, which means you buy them once and re-use them. In the long term, this saves money over buying paper filters.

I tried a K&N air filter in my 2008 Sonata I4 engine, I found slightly better throttle action but the gas mileage dropped by about 1 mpg. I am back to using the paper filter now.

You cannot pass more air without passing more dirt, and dirt is lethal to engines. If the engine failed and Hyundai found evidence of a K&N being installed, do you think they would honor the warranty?
