This guy in Bulgaria seems to be very knowledgeable, That air filter must be the best thing for the price available, it would be like what? £200 and for an extra 60 bhp thats wicked, i wish you could get that over here
. I have heard you get a turbanator supercharger, from planet zoob for the cost of 3 little children, this will boost your power to in access of 3000 bhp.
I would say go for it mate
