I've used a K&N in my 1996 Trans Am since day 1 and now at 170k miles I am not noticing any loss in power or compression due to dirt let in by the filter. Same K&N filter too!! I usually clean and oil it every 20k miles or when it starts to look too dirty. I put a K&N in the SRX last year and so far so good. Only noticeable difference was the engine sounds a little bit louder when you rev it up. After install the SRX threw a few codes as the engine computer was adjusting to the increase in airflow, as the air/fuel mixture is now different than when using the stock filter.
