Does anyone know the purpose of the restrictors in the air intake tubes, and the effect of removing them (apart from letting more air in)? I saw one the other day and its a fairly major restriction, Im planning to remove them unless I hear its a bad idea?
i think shazaam was talking about the restrictors being designed to increase airpressure at slower speeds (like putting your finger over the end of a garden hose?) but who rides a 916/998 at slow speeds anyway!!!
I have also fitted a JHP under tank air filter and removed rubber restrictors and front mesh on the nose cone and it does sound nice. And i hope this does not sound stupid but if you start it up and put your ear to the front of the intake and rev it it sounds GREAT!!!!!!!!!
