1. Clean and wash the sponge air filter

Soak the filter in Twin Air's ORIGINAL Liquid Dirt Remover in a tub for 3-5 minutes to cut the filter oil. Remove any trapped dirt or particles.

The most important thing is that the inside of the filter is completely free from dirt particles.

TIP: Do not use gas or other aggressive chemical cleaners! These break down the glue that holds the foam filter together. They also prematurely deteriorate the foam.

2. Rinse the filter

Rinse the filter with warm soapy water, making sure all dirt particles are removed. If necessary, repeat step 2.

Make sure you rinse the filter with clean water to be sure the soap residue is gone.

3. Dry the sponge filter

Place the foam air filter on a piece of paper towel or clip your filter to something clean and let it drip until it is completely dry.

Oiling the filter before it is completely dry will trap moisture inside the sponge cell.

4. Oil the sponge filter

Submerge the filter in the ORIGINAL Liquid Power Filter oil, making sure to saturate the entire filter, coating it evenly. Make sure you apply oil inside and outside the filter.

TIP: Pre-lubricate the filter at least 24 hours before using the engine to allow the oil to penetrate the pores evenly and allow the thinner to evaporate. A recently oiled filter will cause a greasy carburetion and decreased performance.

5. Eliminate the excess

Squeeze the filter gently so that the excess oil from the filter falls out and a light film of oil remains. Continue massaging the filter until the filter is evenly coated.

TIP: Do not find alternative methods to drain the excess oil. It's best to massage the oil through your pores with your hands.
You can gently fold the filter and squeeze out the excess oil.

6. Install the air filter

Install the cage into the filter and install the filter into the airbox. Before installing, check the carburetor boot for dirt.

Make sure you wait 24 hours for the oil in the filter to dry properly before riding.

TIPS FOR CARE OF THE AIR FILTER

Clean the air cleaner cage and bolt

Using contact cleaner, spray the filter cage and the
bolt to remove old oil and dirt.

Clean the sealing ring

Spray contact cleaner on a rag or towel and wipe the airbox sealing ring to remove dirt and oil residue. Look inside the airbox to make sure no dirt fell into the airbox when you removed the filter.

Cleaning the airbox

Install your Twin Air Airbox Cover before washing your motorcycle or ATV. With the AirBox Cover installed, you can flush your airbox without getting dirt or water into your airbox.
