I went through a K&N phase in 2004. I also don't notice any advantage to using them. I've since been using Wix or other cheap alternative. As long as it fits and is durable enough, it works for me.What about engine air filter? Is K&N 33-5049 the only option we have for high flow aftermarket filter? It needs to be oiled and it costs $60. I had Upgr8 aftermarket dry filter in my previous Scion and it was just $10, but it worked as good as K&N.
To each their own. We have really bad pollen around here, so I do mine annually in my cars. Haven't tackled the TourX yet, but when I do it I can create a how-to post.Replacing the cabin air filter after a year is a bit too soon if you ask me. According to the owners manual it should be replaced every 22,500 miles.
I would agree, but I did notice a significant difference when I installed high flow aftermarket engine filter in my previous car. Sure it was a weak 1.8 liter Scion, so I wonder if it makes any difference on our cars. If K&N is good for ~50,000 miles, it is worth the investment. OTOH, those filters probably cost around $3 to manufacture, so they are making a huge profit.I went through a K&N phase in 2004. I also don't notice any advantage to using them.

K&N also has a reusable cabin air filter which does not need to be oiled. Here:
