We all know how incredibly hard it is to find an airbox/snorkel off of an original 914-6. Here are two airbox / snorkel combos that will fit 6 cylinder applications: First with the longer snorkel is priced at $600 shipped. Second has had the snorkel shortened, a popular modification and also has had the venture area cut out. Since this area is not part of the sealing it does not impact performance. This box is priced at $350 shipped.
The final pic is of some used carb housings. These need restoration and some clip tabs welded on plus clips. These are priced at $50 shipped.
