An air filter felt element ostensibly for MGA 1500 1600, austin healey BN1 BN2 BN4 for wire mesh coopers repro.  

However, the felt is a quality/high-pass desirable for filtering... so it could easily be used in other applications, and so I give you the dimensions.  It is an approx circle of 120mm outer, the folding-leaves are about 15mm, the height is about 45mm and there are about 30 of the folded-leaves around the circle. It has an inbuilt wire mesh that makes it more substantial than felt alone would be. This also means the circle could be made a greater diameter than 120 mm if you wish, as this built-in mesh also adds resilience to the felt structure. (eg 150mm would not be stressful to it at all)

To look for items in my shop, the easiest way is to save any one of MY 2500 items in your watchlist... Then,  whenever you want to peruse my 2500 items... simply click on the hyperlink called “visit store” at the top right of this item. That will take you to a page with my 40 store categories... click the category,  and that category will be displayed with photos on the right... thus a “window-shop”.

Plodding through the Ebay mire of the general search box... or the “see other items” hyperlink  is simply the way to insanity.

If you’re using Ebay’s useless mobile app, I’m sorry... I have no idea how you will find them… this app is a real shocker/compromise in quality and half the stuff is missing. Go to your PC is my advice.
