Happy Easter - Just for reference some notes and photos about this air filter . I its not available anymore, so appreciate its late :0)
have one and quelle suprise it wouldnt fit into the standard air box my S1 was fitted with . Shown is the standard GRP box fitted to the car , which has matching dimensions to the carbon one that I bought and fitted years ago.
As it wouldnt fit in the airbox, i didn’t bother matching it up to the throttle bodies.
Mine has the later " straight ? " type as opposed to the earlier " swan neck " throttle bodies. fitted to the Elise 190 sport. Maybe it fitted on that ?
When I had it put on the rollers at Emerald for the Emerald , I had just one " Witches Tit " filter fitted directly into the mouth of the airbox. It made 196bhp at the crank.
Photos for your ref. Hope this helps & questions please don’t hesitate
