I have had first hand experience of these on a 540 bmw and it was pants, cost him in exfess of 400 to get it all sorted and it was a load of turd.
 
lol, i wish i had money to burn so i could actually buy one just to experiance it and see what shite it was
 
Its a cone filter with a fan in it (isn't it?).

If it sounds too good to be true, it usually is. Hopefully its better than a dirty OE panel filter, but I haven't seen any rousing endorsements from people in motorsport whose opinions I'd respect.

You'd be better off wiping your @rse with 8 £50 notes.
 
it's brilliant I fitted one and got 6hp increase......which is even more amazing when you consider I fitted it to my 8hp petrol mower.

Next week I'm going to put a free flowing exhaust on her too

i've got a high lift 2 lobe cam and a methane blown cyl head spare if you want another 40bhp :lol:



i feel a rival to the :trolley: thread coming on :think:
