K&N Engine Air Filter for Polaris — PL-1003 Washable High-Flow Replacement

The K&N PL-1003 is a washable, high-flow replacement air filter designed to boost airflow and shield Polaris SxS and ATV engines while delivering long-lasting, reusable protection.

Built from multiple layers of oiled cotton gauze and finished with precision sealing beads, this K&N high-flow air filter fits a wide range of Polaris Sportsman and Scrambler models. It is engineered to allow more air into the intake than many stock elements while still trapping dirt and debris, and it’s serviceable—wash and re-oil instead of frequent replacements. Whether you ride trails, work properties, or explore dunes, the PL-1003 balances improved breathing with durable engine protection.

How will this filter affect my vehicle’s performance?

The PL-1003 is engineered to increase airflow through the intake, which can help the engine breathe more freely. Riders often notice improved throttle response and smoother acceleration under load, especially when stock filters are clogged or restrictive.

• Higher airflow design for improved engine breathing.
• Possible gains in throttle response and acceleration.
• Works without needing immediate fuel-system changes in many setups.

What does the PL-1003 use to protect the engine from dirt?

Layers of premium cotton gauze are treated with a tackifying agent that captures contaminants while still allowing increased airflow. The filter’s construction and custom seals help prevent unfiltered air from bypassing the element, so particles are retained before reaching the engine.

• Multiple oiled gauze layers trap fine dust and debris.
• Tacking treatment improves particle capture efficiency.
• Application-specific sealing beads reduce bypass risk.

How do I maintain and service this K&N filter?

The PL-1003 is washable and reusable, designed for routine cleaning rather than disposable replacement. When maintenance is due, remove the filter, clean with a suitable cleaner, rinse, let dry, and reapply filter oil per the manufacturer’s instructions.

• Clean with K&N-approved cleaner or mild degreaser.
• Rinse thoroughly, air dry, then re-oil evenly.
• Reusable design reduces long-term replacement costs.

Will this fit my Polaris model and install easily?

The PL-1003 is made to match OEM dimensions and sealing points for many Polaris Sportsman and Scrambler model years. It uses seamless sealing beads and custom seals for a precise fit, simplifying installation for most owners.

• Application-specific shape and sealing beads for OEM-style fit.
• Direct-fit replacement for many 2014–2026 Polaris models listed in compatibility details.
• Installation generally requires no modifications.

Who is this for? The K&N PL-1003 suits owners of compatible Polaris ATVs and side-by-sides who want a durable, serviceable air filter that improves breathing while retaining strong contaminant protection. It’s ideal for riders who prefer the lower lifecycle cost of a washable element, people who frequently ride dusty trails, and anyone seeking a direct-fit performance upgrade without complex tuning or permanent engine changes.
