K&N Performance Air Filter – 33-3117

The K&N 33-3117 is a drop-in replacement air filter designed to slot directly into your existing airbox – no modifications needed. Unlike standard paper filters that you throw away and replace, this filter is made from layered, oiled cotton gauze that can be cleaned and reused for the lifetime of your vehicle.

The cotton gauze construction allows more air to flow through to the engine compared to a standard paper filter. More airflow means the engine can breathe more freely, which can result in modest improvements to throttle response and overall performance. It also traps dirt and contaminants effectively, protecting your engine in the process.

Built to Last, Easy to Maintain

One of the biggest practical advantages of a K&N filter is that you only need to clean it occasionally under normal driving conditions – far less frequently than you would replace a standard disposable filter. Over time, this makes it a cost-effective upgrade. K&N back this filter with their lifetime limited warranty, which reflects the confidence they have in the product’s durability.

• Washable and reusable – no need to keep buying replacement filters
• Pre-oiled and ready to fit straight into your factory airbox
• Multi-layer cotton gauze media filters contaminants while improving airflow
• Backed by K&N’s lifetime limited warranty

Because this filter reuses rather than replaces, it also reduces the waste associated with disposable filters – a small but worthwhile environmental benefit.
