bag comes with it and its really fiderly, instructions are good but fitment is crap, rob @ssc has had to make a bracket up,

ive been messing about with mine for weeks and finaly got it perfect,

dont forget disconect your battery, then go for a 30min drive cycle so the ecu can get use to the extra air,

or you will get boost problems like i have,

still havent had time to do the drive cycle
