From the French performance parts maker Doppler comes this interesting power filter. It has three ducts in, two of which are blanked off at factory and can be opened for more flow (and more noise!). Employing Bernoulli's Principle, this filter has been specifically designed to improve induction at all engine speeds.
Resembling a normal pod filter in shape, it has a clear cover and ducting to improve air flow while not being as noisy as a regular pod filter. It is also more resistant to water soak than other pod filters.
Mounting size 36mm (also comes with reducer for fitting to 28mm diameter carbs)
