It's simply to force you to leave the engine running for a predetermined amount of time after you have taken the keys out of the ignition to give your turbo(s) time to spool down and cool off a bit before the oil feed is cut when the engine shuts down.

It simply amazes me the amount of people that buy "performance" parts that have absolutely no idea why they've bought them lol!!

 

lol.....the bloke at halfords told me i d get an xtra 50 bhp!!!!!!
