The threaded stud bolt supporting my ADB induction pipe has (as others have experienced) given up on the job and dettached itself from the inner wing! I suspected something ws a miss 'cos on 1 gear pull away there was a single knock each and everytime coming from the engine. Upon inspection the above was diagnosed. Will look at what repairs can be carried out at the weekend!

Move the LAN pipe closer to the MAF (under the hose) it will hold it tightly + it wont rattle or fall off!

If you are more organised than me you could contact bighead.co.uk and get a 'free sample' of their bolts (as recommended by ChrisH) which will do the same job.
