Fitting Air Filter

We received the air filter for the car today that we ordered from Summit racing in America. Mark got onto fitting it straight away. Originally we had to measure and make sure the filter we order would fit underneath the bonnet with enough clearance and space. We established that the optimum size would be either a round 8 inch diameter or a 8 1/2 inch oval set up with a maximum 3 inches height from the carb flange.
