K&N Performance Air Filter – E-2998

The K&N E-2998 is a high-flow drop-in replacement air filter designed to offer better engine breathing compared to a standard paper filter. It fits directly into your existing airbox – no modifications needed – making it one of the simplest performance upgrades you can make to your vehicle.

Unlike disposable paper filters, this K&N filter is made from layers of oiled cotton gauze. This construction allows more air to flow through to the engine while still trapping dust, dirt and other contaminants before they can cause harm. More airflow means the engine can work more efficiently, which can contribute to modest improvements in throttle response and performance.

Reusable and Long-Lasting

One of the biggest advantages of a K&N filter is that it is washable and reusable. Rather than replacing your air filter every year or two, you simply clean this one and put it back in. Under normal driving conditions, cleaning is only needed infrequently – making it a genuinely cost-effective choice over the life of the vehicle. K&N back this filter with their lifetime limited warranty.

• Drop-in fit – installs directly into your standard airbox, no cutting or fabricating required
• Oiled cotton gauze construction – improves airflow while filtering out harmful particles
• Washable and reusable – clean it, re-oil it, and it is ready to use again
• Lifetime limited warranty from K&N

Choosing a reusable filter also means fewer disposable filters ending up in landfill – a small but worthwhile environmental benefit.
