Are the twin trumpet air filter boxes for early Stags a sort after item.

I don't know who would desire one Sujit? It looks like it is more restrictive and it does suck in hot air after all..

No plan to use it but now will remove those lock down clips for my other air box.

Dear Sujit,

I don't believe that they are particularly desirable unless someone is trying to build a 'proper' first series production car. They were only fitted to the first 2,500 or so cars (and none for the USA). If you wanted to give me one (ho ho !) then I would gladly accept it and put it on the shelf until I get round to building an engine for one of my early cars (but I wouldn't hold your breath) but you aren't in the UK are you, so giving me one would be difficult (even bigger ho. ho.). There were two designs of these - flattened ends and round ends but I have no idea which should be fitted to which cars (there are pictures of press cars from 1970 with each fitment).

To answer S-type R - it only sucks in hot air from the rad area, similar to the later fitment, but doesn't have the 'elephants trunk' so doesn't suck in really hot air, and doesn't have the temp control valve in the base of the filter box to control this.

This probably doesn't help but don't throw it away if you have one as someone, somewhere will want one eventually.

The reason the 2 trumpet air filters were modified was because the first ones were round and it was found they would foul the underside of the bonnet in certain circumstances when the engine moved upwards, so the tops were flattened to allow more clearance.

Hello Peter,
I'll hold on to it and take it to UK on my next trip. It came off a K reg car that was imported into the US. The trumpets are flattened.
