K&N Sealing Grease air filter sealant 6 oz tube — heat-resistant, pliable airtight seal

This tube contains 6 ounces of K&N-formulated sealing grease that helps close gaps between air filter bases and housings to reduce air leaks and maintain proper filtration performance. Engineered in the United States for automotive use, the grease tolerates elevated temperatures commonly found around the intake area while remaining pliable enough to form a reliable bead on sealing surfaces. Note: this grease is not recommended for use with clamp-on style filter elements.

How does K&N Sealing Grease improve filter performance?

The grease fills small gaps and surface irregularities where unfiltered air might bypass the filter media, helping the filter maintain its designed airflow path and performance. It forms a continuous sealing bead that resists compression set and preserves the seal under thermal cycling.

• Reduces unmetered air entry around the filter perimeter
• Maintains a flexible seal despite engine bay heat
• Easy to apply in a continuous bead for uniform contact

Where and how should I apply this sealing grease?

Apply a continuous, thin bead to the sealing surface of the air filter base or the filter housing where the two surfaces meet. Clean the mating surfaces first, press the filter into place, and allow the grease to seat as you tighten any mounting hardware to produce an airtight fit.

• Use on filter bases and housings with flat or molded seals
• Not for clamp-on filters — avoid use with clamp-style fitments
• Wipe away excess with a clean cloth before final installation

Will the grease withstand engine heat and weather exposure?

K&N’s sealing grease is formulated to resist common engine bay temperatures and maintain adhesion through heating and cooling cycles. It resists becoming brittle or overly runny, so the seal remains effective across typical operating conditions.

• Heat-resistant formulation for intake-area temperatures
• Remains pliable across temperature swings to preserve seal
• Durable against short-term moisture exposure in normal use
