There used to be a lot of these filters in the UK. They're known as pancake filters and have a waxed string coil inside them acting as a filter. The earlier ones had a fine wire mesh which you'd wash out in petrol every now and then.
Not sure bought them secondhand off @Evil Mitch , yes the pipes are TORS hooked up to the OEM collector , im not chasing HP with this set up , aesthetically pleasing to the eye and ear is whats important to me.
I havnt ridden it since installing those in any thunderstorm deluges, normal type showers havnt effected them , there are K&N type elements available from the states i just havnt gotten around to buying any as yet.
