Ive always thought the ones available are are a bit compromised for the limited space on a mini so I Have made my own
I wanted the longest possible pipe for the space available & a decent box filter around it
I got a bare spinning & some scrap alloy for a base which I cut & drilled to match the carb face. Done some aluminium welding for the 1st time a bit messy but seems to have penetrated OK
for the filter I used a blank baseplate so I could mount it sideways to suit the car as the wiper motor is quite close. have only done a short road test so far but there is definitely a noticeable increase in power plus it sounds a little quieter than the old K&N one

Will have to get it rolling road tested now<br>
