Chris If you put K&N's on be prepared to change the carb needles (you need richer to balance out the increased air flow) and would also benefit from heavier carb springs (yellow coded ones from memory). This stops the carb needles rising too rapidly when opening the throttle, thus giving smoother response.
Pat Subject: K&N for HS4s Does anyone know what the K&N part number is for air filters that would fit a Spitfire 1500 with SU HS4s, or a cheap place to get them in the USA?
