Stick with Bosch...It's your best bet. Try to get something platinum if at all possible. Like Platinum 4's....however they run about $60 after tax for the 4 of them.
NGK makes some nice plugs too....
Iridium is the newest technology in plugs, so that may also be a route you want to explore..

explain the process for spark plug change 2.0 engine
If you mean it is only running on 3 cylinders, you should check your spark plugs, spark plug wires and the distributor.
Disconnect the wires to the battery, remove the spark plug cables and boot covers, and remove the old spark plugs. Next, put in the new spark plugs, attach the boot covers and spark plug cables and reconnect the wires to the battery posts.
Very easy. You have to pull the engine cover off. then pull the coils off and unbolt the plug.

None. Champion plugs should NEVER be used in a GTI. They will carbon up your cap and rotor and cause nothing but problems. You should only run Bosch or NGK copper plugs.
