Need some battery help. I am into installing a Luna dual battery system into my 40 and I cant get the 2nd battery under the hood. I am not a mechanic at all. I can change oil thats it. I want to get rid of all the air filter **** sitting on top of my engine, I am attaching some photos one of how it is now, another of where I want to put the yellow top, and then finally a third showing the air filter **** that I want to get rid of. My question is what do I need to do to get rid of all this stuff. What type of much smaller air filter can I buy? I hope the pics help bc I wont be able to speak intelligently about anything you might throw at me. Let me know your thoughts and thanks in advance.
