Tusk First Line Foam Air Filter Oil 13 oz (2 Pack) –

Tusk First Line Foam Air Filter Oil (13 oz, 2-pack) is a sticky, water-resistant spray oil formulated to trap dirt and dust for foam air filters used in dirt bikes, ATVs, UTVs and other powersports machines.

When you ride in dusty, muddy, or wet conditions the last thing you want is abrasive grit or water getting past your foam filter and into the engine. This two-can pack gives you repeatable coverage or a spare can for the next service, and its spray formulation helps deliver even saturation across foam layers without over-applying. The result: improved filter performance, longer filter life, and reduced risk of engine wear from airborne contaminants.

How does this oil improve foam filter performance?

The Tusk First Line formula adds tackiness and water resistance to foam filters so airborne particles stick to the filter foam instead of passing through. Its consistency balances tack and airflow so you don’t choke the filter while still capturing fine dust. Regular, even application restores a used filter’s ability to trap contaminants and helps avoid premature engine abrasion.

• Creates a sticky surface that captures dust and fine particles.
• Water-resistant properties repel moisture that could carry grime.
• Spray applicator for consistent, even coverage across foam.
• Helps extend the effective life of foam air filters.

Will this work on my dirt bike, ATV, or UTV foam filters?

Yes — this product is formulated specifically for foam-style air filters common on motocross bikes, ATVs and UTVs. It’s designed to penetrate and coat foam pores without dissolving or degrading the material. Use whenever the filter is cleaned and dried to restore trapping capability and maintain engine protection between services.

• Compatible with all foam air filters used in powersports vehicles.
• Safe for repeated use after cleaning and drying the filter.
• Two cans provide a spare or allow treatment of multiple filters.

How should I apply the spray for best results?

Shake the can well and hold it several inches from the filter so the spray lands evenly, saturating all foam surfaces. Work the oil into the foam by gently massaging or squeezing until the color evens out; avoid over-saturation that can restrict airflow. Allow any excess to drip off, then reassemble the filter once tack and even coverage are achieved.

• Shake can thoroughly before use and spray from several inches away.
• Coat inner and outer foam layers evenly; massage for full penetration.
• Let excess run off and dry tacky before reinstalling the filter.

How durable is the protection in wet or muddy riding?

The formula is designed to resist washout and stay tacky when riding in wet or muddy environments, so it continues capturing dirt rather than letting it pass into the intake. While not a permanent seal, the water-resistant properties preserve filter effectiveness through typical riding conditions and help minimize contamination during a ride.

• Water-resistant for better performance during wet rides.
• Helps prevent mud and water from carrying particles past the filter.
• Reapply after heavy water exposure or scheduled cleaning for continued protection.

Who is this for? Tusk First Line Foam Air Filter Oil 13 oz (2-pack) is aimed at riders, mechanics, and powersports enthusiasts who service foam air filters on dirt bikes, ATVs and UTVs. It’s a practical choice for weekend trail riders, competitive racers, and fleet owners who need reliable filter protection, consistent application, and the value of a two-can supply to keep machines protected between services.
