Just stumbled across this in one of my car magazines i purchased from the uk when i was there. Its called a NOS 'SHOW' PURGE KIT. Basically replecates a nos purging system without the power gain thru your engine.
Cost is like 300 british pounds which is like 1000 aussie dollars, prolly better off buying the proper kit?
What will they think of next?
