$6 Airbox heat shield
Some companies will charge $150 and up for this "miracle mod" and claim to increase power by 4hp. Whether you believe this or not, it is based on a sound evidence. The theory behind this mod is by adding a reflective insulation covering you will lower the temperature inside the air box;. This works on the premise of reflecting radiant heat. You'll also see the same theory being used in your house around the hot water heater.
The cheap and easy way to do this yourself is to go to the hardware store and pickup some reflective insulation tape.
