| This is a complete air cleaner for one carb. If you want air cleaners for both carbs then be sure and order two of these units. It is a cleanable and reuseable filter element, so you'll never have to buy another air cleaner. These filters are guaranteed for a million miles by the manufacturer as long as you take care of them properly. These are set up to work on the stock SU which is a 40mm carb. This unit will not work on the 4 cylinder dual SU style carbs without mods. If we happen to be out of stock please allow an extra week for delivery. Last update 12/09 |
