These instructions will show you, step by step, on how to clean
your air filter. A clean air filter will allow a constant clean
flow of fresh air to flow freely into your engine, boosting engine
performance. It will also prolong the life of your engine by
reducing the risk of dirt and dust from getting into your engine.
The first step is to remove the air filter from your engine.
Next, remove the foam filter element from the rubber base.
Rinse the foam filter element, from the inside face, with nitro
fuel to remove all the dirt and dust. Make sure you do this in a
well ventilated area.
Below is what the clean foam filter element should look like.
Apply air filter oil to moisten the foam filter element. You can
purchase air filter oil at your local hobby shop or use Marvel's
Mystery Oil (available at most hardware stores). Apply an even
amount of oil over the foam filter element. Use your fingers and
squeeze the foam filter element to ensure that the oil is absorbed
throughout the foam filter element.

apply the filter oil
Reinstall the foam filter element into the rubber base, make sure
there are no gaps between the two elements. You do not want to
leave any gaps for dirt or dust to seep through.
Above is a properly fitted foam filter element, with a tight fit
all the way around. Below is an improperly fitted foam filter
element with a gap that would let dust and dirt seep in.
Reattach the air filter onto the engine. Ensure the air filter fits
snugly onto the carb.
