Product Information

Full details

The Twin Air foam air filter is designed for serious off-road riders using Gas Gas motorcycles who require a balance of high-flow performance and reliable engine protection. Its primary benefit is a dual-layer foam construction that traps both coarse debris and fine dust particles, ensuring consistent horsepower delivery during intense riding sessions. Potential users should note that, as a high-performance foam filter, it requires consistent cleaning and re-oiling to maintain its filtration effectiveness and longevity compared to disposable paper alternatives.

Extended Product Information

FAQs

Can I use engine oil to oil this filter?

No, you must use a dedicated foam filter oil that is designed to stay in the foam and trap fine dust particles.

How often should I clean the filter?

Clean it after every ride, or more frequently if you are riding in exceptionally dusty or muddy conditions.

Is this filter pre-oiled?

Most Twin Air filters are sold dry; check your specific packaging, but generally, you should apply your own oil before the first use.

Why is there minimal stitching on the filter?

Minimal stitching reduces the number of potential leak points, increasing the overall structural integrity of the filter.

Does this filter fit all Gas Gas bikes?

This specific model, 723.18.82, is designed for specific Gas Gas applications; always verify your specific bike model and year against the part number.

What is the best way to clean the filter?

Use a dedicated foam filter cleaning solution and warm water, then allow it to air dry completely before re-oiling.

Troubleshooting

Visible dust inside the air boot

Check the filter seating to ensure no gaps exist and verify that the filter has been oiled properly.

Engine performance drop during a ride

Check the outer layer of the filter for heavy debris buildup and clean if necessary.

Foam feels dry or brittle

The foam has aged or been damaged by improper cleaning agents; discard and replace with a new filter.

Setup, Compatibility & Care

To install, ensure the airbox is thoroughly wiped clean of any loose debris before inserting the filter. Apply a light layer of grease to the sealing ring to ensure an airtight fit against the airbox frame. For cleaning, use a specialized foam filter cleaner; avoid harsh solvents that can degrade the foam structure. Once cleaned and dried, apply an even coat of foam filter oil by massaging it into the foam until it is fully saturated but not dripping. Squeeze out any excess oil before reinstallation. Replace the filter immediately if you notice any rips, tears, or hardening of the foam material.
