A revolutionary new filter with an aluminium heat shield which helps to funnel as much air into the filter as possible. The shield helps to create a vortex to maximise the air flow through the filter, it also acts as a shield to protect it from engine bay heat. The top of each filter has a moulded twist in it to help spin the air into a vortex for improving air flow through the filter.
