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.

Twin Air's high quality materials and superior construction deliver unbeatable performance and protection. The hands-down choice of more World and National Champions than all other filters combined.

Twin Air's fused layers of open-pore foam and fine inner foam trap even the smallest particles-without restricting airflow.

Extra dirt protection for your K&N filter. Our custom made oiled-foam filter sleeve wraps snugly around the K&N filter to give a first layer of protection against dust and dirt. Oil it like you would any other foam filter.

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.

Superior Filtration:

This should be the last oil filter you will ever buy. Made from laser cut, medical grade, 304 stainless steel micronic filter cloth, this filter provides 200% more filter area than other filters in many cases. Most good paper filters will pass particles in the 90 to 95 micron range, and some tested, as much as 300 microns. Sand is about 125 microns and a white blood cell approximately 25 microns. Scott's stainless filter catches items down to 35 microns "absolute". The pleat seam is welded, able to withstand up to 600 degrees, not glued, like paper filters.

• Cleanable and reusable filter
• 35 micron stainless steel mesh
• Stainless check ball and stainless spring
• CNC aluminum caps front and rear

The PSR Oil Filler Caps are CNC machined from high quality aluminum and come with an E-clip that is already safety wired to a mounting tab. The wire is covered with silicone tubing that will not melt or discolor. Available in silver, black and gun metal.

Warp 9 CNC billet machined Oil Filler Cap. 

Available in Blue or Black and it includes a new O-ring

To make removal as easy as possible, the center tab takes a 12mm wrench perfectly, or a 1/4" ratchet drive in the center. 

On each end of the center tab is a drilled hole should you find it necessary to safety wire your filler cap in place.
 

If you need a replacement cap for your Acerbis tank, why not go bling? These caps have a carbon fiber pattern molded into them that is extremely realistic. Looks like the real thing. Topping off the cap is a CNC Machined metal vent cap. This eliminates the need for a lengthy vent tube that gets in the way. The vent cap allows air to vent into the tank but does not allow fuel to splash out during normal use or during a tip over.

  These caps fit Acerbis tanks only.
