Stock Twins King
I just installed my new HKS polished intake pipe onto my drop down intake system. This system can only be done if you have a FMIC, because you use the area where the OEM IC used to be for the filter. I have a 10" K&N filter below. This prevents any engine heat going into the cold air intake. The actual cost is under $100 if you don't mind cutting into your car. It's a mod that you really can't reverse later.
