Mobile 1 on sale for $28 -5 qt bottle, 3.75 for another quart. Bosch premium filter on sale $6.99. Comfort in knowing what's really going in/on my car by doing it myself. Priceless.
What kind of audio kit? What are you trying to do? A little more information would be helpful. I have no way of knowing what that remote is for or what you are trying to control with it or if it is even compatible.
