K&N Performance Drop-In Air Filter – 33-3036

The K&N 33-3036 is a high-flow, washable replacement air filter designed to slot directly into your standard factory airbox – no modifications needed. It replaces your existing disposable paper filter with a reusable cotton gauze filter that allows more air to flow into the engine, which can contribute to modest gains in performance and throttle response.

Unlike standard paper filters that are thrown away and replaced, this K&N filter is built to last the lifetime of your vehicle. When it gets dirty, you simply clean and re-oil it using a K&N cleaning kit, then refit it. Over time, this makes it a more cost-effective choice than repeatedly buying disposable filters.

How it works

The filter uses multiple layers of oiled cotton gauze – a fine mesh material that traps dirt and contaminants while still allowing a strong flow of clean air into the engine. More airflow generally means the engine can breathe more freely, which supports better performance and efficiency. The cotton layers are treated with a specially formulated oil that helps capture fine particles without restricting airflow.

Key benefits

• Reusable and washable – clean it rather than replace it, saving money over time
• Drop-in fit – installs directly into your existing airbox with no cutting or fabrication
• Comes pre-oiled and ready to install straight out of the box
• Backed by K&N’s lifetime limited warranty (limitations apply)
• Reduces waste compared to single-use disposable filters

Under normal driving conditions, this filter only needs cleaning infrequently – making it a genuinely low-maintenance upgrade. It is one of the simplest and most accessible performance improvements you can make to a car.

This filter fits a range of vehicles. Use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific make, model and engine before purchasing.
