Hi Getting time to replace the air filter on my 23 IS350 F sport. It has the factory cold air system Is it worth getting something aftermarket, or just a cartridge replacement. And what is the best low restriction cartridge? K & N? Is the oiled filter a problem? I ask because I put one on my 2006 HHR and got codes, that some people said were from the oil contaminating the sensors.
I was looking at WIX
Thanks
