BMC air filter & ECU upgrade

Also, if it is advised to use the conical type filter, how do you know which one to buy? I have visited their website and have no idea on these filters. It simply gives you the model number of the flat style filter, but not for the conical type.
Anyone try the EvoSport ignition upgrade?
Thank you!
I'll let you know on the evosport performance ignition stage I soon.
