PJ1 Foam Air Filter Oil Spray 13 oz — Super-Tacky, Water-Repellent Oil for Foam Filters

When you depend on a foam air filter to protect a high-performance engine, the right oil keeps contaminants out without restricting airflow. PJ1 5-20 Foam Air Filter Oil Spray is formulated to cling to foam media, creating a tacky barrier that captures harmful particulates before they enter the intake. Packaged in a convenient 13-ounce aerosol, this spray is designed for quick, even application and to reduce messy drips or waste.

How does PJ1 5-20 improve foam filter performance?

The spray’s super-tacky chemistry increases the filter’s ability to retain dust and abrasive particles, improving filtration efficiency without compromising airflow. Its non-settling formula keeps the oil evenly distributed across the foam over time, so the filter performs consistently between services.

• Creates a sticky surface to trap small particles
• Maintains even coverage—resists separation or settling
• Designed to balance capture with airflow for better engine protection

Will the product resist water and not gum up the filter?

PJ1 5-20 is formulated to be water-repellent, so it sheds moisture that can otherwise degrade filter performance or lead to uneven distribution. The spray is non-settling, which helps prevent clumping or hardening on the foam that could restrict airflow.

• Water-repellent finish reduces moisture absorption
• Non-settling formula avoids hard deposits and clogging
• Helps preserve consistent airflow and filtration over time

How easy is it to apply and how much waste will I have?

The aerosol design makes application fast and controlled so you can cover the filter evenly without excess dripping or pooling. PJ1’s spray format minimizes product waste compared with pour-on oils or messy immersion methods, making it practical for quick maintenance or full filter re- oiling.

• 13-ounce spray for controlled, even application
• Less dripping and runoff than liquid pour-on products
• Simplifies routine service and reduces cleanup time

Who is this for: PJ1 5-20 Foam Air Filter Oil Spray is intended for riders, mechanics and enthusiasts who use foam air filters on motorcycles, ATVs, UTVs, off-road vehicles, lawn equipment or other small-engine applications. It’s suited to anyone wanting a tacky, water-repellent oil that reduces abrasive particle ingestion and keeps the filter performing reliably between cleanings. Avoid using on filter types not designed for foam-oil treatment; follow manufacturer guidance for your specific filter material.
