Filters in Competition

The Abingdon Trophy (1.8i & VVC) and Moss International Speed Chamionship Standard class allows the fitment of any after market filter and cold air induction system sold with that kit. Note that there appears to be some ambiguity regarding home made kits, but at present these do appear to be allowed.

For competitors, only the best filters will do- and the best two are available from K&N and Ramair
