I have put a K&N in every car I have owned for 15 years. I find it to give just a hint more responsiveness and a hint better tone. While I have never put any car on a dyno and checked, I just like not having a cheap paper filter. Get the cleaning kit so you can properly clean and lube your filter and check it every 3-6 months for contamination. It will impact your mileage if it gets dirty/clogged. Won't go without in any car!
