this is the advantage bmc claim to have got on a dyno

you realy wont notice any difference in power.....but a bmc is deffo the one to go for

some one was telling me that a new air filter wont make a difference unless the ecu knows that there is an increase in air in the engine otherwise it wont make a difference or it could make things worse.

is this correct??

potentially yeh, you would need a remap to get the full effect of a BMC, but a remap is really only benificial(due to its cost) if you have a number of engine mods, meaning you'll get the maximum effect of all the engine mods together.

Go for the BMC or K&N Apollo, they are the most expensive for a reason! I'v only ever seen them in the top 3 when its came to comparisons etc
