i think both parts came to about £30 inc. VAT.
the difference in the size off the inlet hose / funnel is twice the size of the original, so its gotta be good!
the bit which is screwed to the car to which the hose adaptor clips into has a massive fixed flap which halfs the size of the inlet, you can't miss it!
i cut that out and filed down any rough edges after reading fellow beeza owners doing the same!
i also put in a Green cotton filter (JBS £37 delivered, and its a stock item
so that also arrived within 48hrs
)
the 3 mods together did make the throttle response better, probably down to the air being allowed in quicker, which i assume increased bhp!
only by a couple of horses probably, but every little helps!
for the cash outlay and an hour to cut that flap out, i'd reccommend the mods!
