Wraps around your K&N filter to keep water and small particles out of the filter itself. K&N DryChargers are manufactured from a durable polyester material and are pre-treated with a proprietary hydrophobic process designed to prevent splashes of water or mud from saturating your K&N air filter. The DryCharger will also stop small dirt particles; yet add little restriction to the airflow of the filter. The DryCharger can be installed under the Foam Wrap.

Pre-filter only, K&N air filter sold separate.

This seal helps keep debris and water out of your DR650 air box and it may become damaged or missing over the years. It is an important part of your DR650's intake system to maintain & prolong air filter life.

Simply, remove the air box door, then remove the old seal and clean out the track it sat in. Set the new seal in place and cut off any excess material remaining. Install the air box door and you are done.

FunnelWeb ProLine Filter Highlights:

• Optimum air flow for increased riding time
• Improved engine protection
• Extended filter change intervals
• Simple to install, clean and re-oil
• Easy fitment

Like all FunnelWeb filters, the ProLine Filter features profile cut, single layer, single density foam that doubles the external surface area of the filter without increasing the original filter size. The ProLine Filter traps dirt, dust, sand and mud over a larger area on its outer surface, ensuring optimal air flow is maintained for maximized engine performance and reliability.

The single layer, single density polyurethane foam has the added advantage of being easy to clean and the ability to maintain its original shape after numerous washes. Overall, compared with conventional foam filters, FunnelWeb offers more protection from dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.
