Intercooler Cleaning

[Mark Pollan <Mark.POLLAN@MCI.COM>]

With all this talk about oil on the intake system, how would one go
about cleaning all that crud out of the intercooler?  It has to be
affecting efficiency to some degree.

Also, I just got off the phone with VW Parts about fuel injectors. I
asked Eric about the viton tipped that apparently superseded the metal
tipped ones. He said the viton rubber referred only to the o-ring and
there is just one shrouded injector type. What am I missing as I just
recently received what look like metal tipped. The part I received was
035 135 551C. I recall a different part number of 035 135 551F for the
new ones.

As you can see I'm a bit confused.
