Hi Tony - The only multi-carb air cleaner that I've seen was one custom made by an Inliner many years ago (Sorry, don't remember the issue). He did, however, use a K & N air filter No. E2960 that is 24 inches long, 5+ wide and 2+ high. The K&N website has a page where you can input dimensions and get nearest sizes. The oval filter is Type F. Find a distibutor (I've used Martel Racing) to get the lowest price - still will cost a bit.
