the silicon one does have a bigger diameter over the whole length; if that increases airflow/performance ?
Very little difference from hoses.... They're better at preventing heat soak and a slightly bigger diameter, but the differences are negligible....
Bigger diameter isn't always good thing though.
deadly serious i hope, just flogged my matched inlets for £20 so i could buy a silicone hose :butt:
They may be a larger diameter, but the throttle is still the same size.....
7hp ? From a silicone bend ?! Not sure if comment was SRS or SCZM. :S
