Single point injection mate. Its the 1171cc Energy engine - very similar in design apart from the capacity to the 75bhp 1.4 RT. My old Mk1 was a 1.2.
Id go for a Hill Power one if I were you. I had a K&N (fairly cheap at £45), but the noise is better on Hill Power ones - lets face it, you dont buy them for power do you!! The airbox sits on top of the head, which has a single throttle body. Rip off the old airbox and place the induction kit just straight on top of the throttle body - and away you go! Youll also need to rip off the warm air pipe that comes from the front of the engine and the temperature control regulator thingy that used to give constant temperature air to the airbox. But keep the old airbox as you might want to sell the car as standard.
