Here is a new red air box by Freeline for use in 100cc applications.  Included in the shipment will be the larger tubes needed for shifter drivers.  Not shown in the photo is a hose clamps appropriate for securing the intake boot in position.

Please examine  this product closely  to insure it is something that you can use. It is better to ask questions in advance than after the purchase.

 I listed karting  items from A- Z and everything in between all listed on ebay only.   These are CLOSEOUT PRICES. Many items are no longer made. NO Returns. All Sales are final.
