Scotty I have three questions: I drive a 2010 Camry. I was going to purchase an engineered air filter and a cabin filter from Toyota. Their prices are much higher than that of Napa and car quest. Is the manufacturer’s products really better than after market? Is coconut oil or olive oil ok to put on the plastics or on the dash of the car? I also wanted to install LED bulbs in the same car but someone said the wiring harness may not support those bulbs, does the wiring harness have to be changed to accommodate the new bulbs?
