Do you have a link for those air filters you have on your type 4 as they are identical to mine , but i cannot find where to purchase that particular size . cheers
They were fitted on my Brosol carb bundle from Big Boys Toys several years ago. I had a quick look for you on VW Heritage who absorbed BBTs and couldn't see them. Good luck with your search
Remember seeing you guys in the services just outside Abbeville when we broke down last summer. Shame you had to sell.
