Ever since I,ve owned my 2011 Argo Frontier I,ve noticed that it retains a lot of heat underneath the hood. When enough heat builds up underneath the hood , the heat then begins to radiate out from the plastic panel thats right below the handle bars. You then start feeling the heat against your legs. The muffler on my 2011 Frontier is a lot quiter than my friends 2008 Frontier muffler. I knew that the quieter muffler was a lot more restrictive ,and this probably had a lot to do with the heat that I was experiecing with my new machine. When driving the Max IV or the Mudd-Ox I never experienced heat like this because the engines were behind you.
I opened up the top of my factory muffler and was amazed just how restrictive it was, and also why the exhaust note was so much quieter than my friends 2008 ,Argo factory muffler. I have since installed a new muffler off of a 2008 Argo Frontier. I also bought an aluminum mounting plate and K&N cone shaped air filter from Performance V-Twins. I mounted the billet aluminum ,air cleaner mounting plate on top of my stock carburetor. The next thing that I did was use different cut sections of truck radiator hose ( part numbers 7820 and 8581 from NAPA auto parts ) ,cut off pieces of steel exhaust tube ,and stainless steel hose clamps to piece them all together. When I had configured the different radiator hose pieces together, I then attached one end to the billet mounting plate, and with the cut pieces that I had left over , I routed the K&N air filter in between the head light and cool air vent thats opposite the muffler. For my initial first test I let the engine run at idle for an hour with the hood on. When I opened the hood I expected to feel a blast of hot air rising and hitting me in the face, but the engine bay was a least 50% cooler after I,d made these modifications.The engine now runs cooler with the hood on, and the exhaust note now has a deeper and stronger tone.

When you brought your big block Argo Frontier to river run atv park I was really impressed at how much cooler your engine ran than mine did when our engines both got hot. When I saw the intake set up that you had made , and how well it worked , thats when I decided to do this to my Argo Frontier.
