Will have my 15k service next weekend. Will let dealership change the oil, while tire rotation is done outside. Brakes have been checked recently when I complained about my tires. So, this only leaves AC Cabin filter. Our 3GS DIY manual suggest either to clean it (w/compressed air) or to replace it. Do you guys think at 15k it should be replaced?

Also, I found in one of the forum's post that we can get Lexus cabin air filter from Sewell Lexus (lexus-parts.com) for a CL discount price of $23.50, down from original $32.50. Anybody knows where to get that discount code?
