Phil_P Posted February 21, 2009 Share Posted February 21, 2009 Have a look at the K&N web site, I seem to remember it has a data section with all the sizes. However, if the W37 is similar to the W32 that I have, you may need to make (or have made) an adapter. I turned a bit of Delrin bar that bolted onto the inlet face of the carb, and the K&N filter fits round the outside of it. It has the added bonus of giving a nice smooth intake 'trumpet' rather than the flat plate that the standard foam filter had. This I hope is rather more efficient.
