K&N's High-Flow Original Lifetime Engine Air Filter 33-5076 is a washable, reusable replacement that boosts airflow and is designed to fit 2018–2026 Jeep Gladiator and Wrangler models.

This performance air filter replaces disposable paper elements with multi-layer cotton gauze to allow more air into the engine while still trapping contaminants. Engineered and made in the USA, the K&N 33-5076 is pre-oiled and ready to drop into the factory airbox, offering a long-lasting, cost-effective upgrade for owners of compatible Jeep Gladiator and Wrangler vehicles. It’s backed by K&N’s limited lifetime warranty and the company’s motorsports-proven development process.

How will this filter affect my Jeep’s everyday driving?

Installing the K&N 33-5076 can improve throttle response and support modest horsepower gains by increasing clean airflow compared with a standard paper filter. Changes are most noticeable during acceleration and under load, while normal engine protection is preserved by the filter’s multi-layer media.

• Increased airflow for better acceleration feel
• Maintains filtration with four layers of cotton gauze
• Pre-oiled and drop-in ready—no special tools required
• Designed to work with stock airbox and intake geometry

How often do I need to service this washable K&N filter?

The 33-5076 is designed for long intervals between cleanings: under normal highway driving it typically only needs attention about every 75,000 miles. Clean more frequently in dusty, off-road, or heavy-use conditions to maintain optimal airflow and protection.

• Typical cleaning interval: up to 75,000 miles under normal highway conditions
• Shorten intervals in dusty or off-road environments
• Re-oil with K&N filter oil after cleaning for best performance
• Reusable—reduces landfill waste compared to disposables

What materials and warranty support this product?

Who is this for? The K&N 33-5076 is ideal for Jeep owners who want a long-lasting, eco-friendlier alternative to disposable filters and who value improved throttle response and sustained airflow—especially drivers of Wrangler JL, Wrangler, and Gladiator models who do street, highway, or moderate off-road driving.
