steviej, my comment about performance gain was more of an FYI than a response to you. I realised that some people were looking or wanting to know about performance gains from these filters. Sorry for the confusion.

I have to agree with skperf. on this one. The increase that may happen in HP will most likely not even be noticable. You will get an increase in MPG although they do come at a price. SK filters are performance filters, which means they are made differently from your regular filters. They let a lot more air through but they also let a lot more dirt in as well. They are nowhere near the filtering ability of the regular filter. You are letting a lot more and a lot bigger particles through. So, while you are seeing temporary MPG increase, you are effectively ruining your engine in the long run. To me it is ABSOLUTELY not worth it. And I may get flamed for this, but if you are looking for performance, ES300 is probably not the best place to start. I love my car, but I got it b/c its quiet, smooth and comfortable. Not because its 210 horses make my blood boil. :)
