my ed30 has been mapped with a pipercross filter and makes 303bhp....
now I was getting some issues with the airbox kept pulling off its mounts due to dodgy rubber and broken pegs! I have replaced all the pegs and rubber, poped the bonnet today and it didn't look right, turns out its now cracked all the underside of the airbox!!
any ideas why? I can only assume its got to much suck and it breaking it
