Power Gain : 5hp
The K&N Filtercharger is probably the easiest, cheapest, and best result-producing mod you can do. The part itself costs
anywhere from $50 to $100. By freeing up the air flow into the engine, more horsepower is able to be delivered to the wheels
because the engine doesn't have to work as hard.
First, go to a local hardware store, and get a tube of aluminum dryer duct. It is the silver tube in the picture. It is
bendable and light weight. Make sure the hose is the same diameter as the K&N Cone and the inlet into the throttle body.
I believe the size is 2". If not, someone please correct me. Simply remove the old air box and intake tube setup. To do
this, remove the bolts holding the airbox into the engine behind the battery, and remove all the intake hoses as well.
Then you clamp the dryer duct to the throttle housing, and the filter to the other end of it. Place it out of the way of
moving parts, and enjoy your new mod!
(NOTE: Make sure the filter is oiled. Most come pre-oiled.)
