Was wondering how to go about helping my m20 the breath better. it's got a K&N on. It,s also running with an FSE boost valve & an Eprom chip. I would like to develop the air intake manifold but I do not know how or, if it's possible?
Cheers Dom

to make it breath better fit the standard airbox back on with a panel filter or a Genuine Bmw filter,Was wondering how to go about helping my m20 the breath better. it's got a K&N on.
