I just recently became a proud owner of a 2007 4runner with a standard SR5 package with a v6. I am pretty impressed with the performance but looking for a little more and get some better mileage. I am thinking about a cold air intake kit and a cat back exhaust but honestly don't know where to start. I am not looking to drop thousands of dollars as that would defeat the purpose. Also, What are some good replacement head lights? I am looking for a very crisp bulb that is bright. Lastly, any ideas on how to restore the plastic on the running boards, mirrors, and strip on rear bumper?
