K&N Filter
 

I have an '03 Rx-300 and was just wondering if anyone has put in a K&N air filter in theirs and if so what changes do you notice (Fuel consumption, power etc.)? I just want to know if it is a wast of time or does it make a noticable difference . Thank you

RE: K&N Filter
 

Waste of time, MONEY, often results oil/dirt contamination of MAF/IAT sensors due to oil wicked downstream, only possible benefit is at WOT and high intake airflow when throttle plate ISN'T the major obstruction/restriction to intake airflow.

Thanks for the input. I really didn't want to mess with anything but a fellow at work said it would help with fuel consumption. I'm not worried about power as there is lots for my needs. Thanks again I won't bother getting one.
