Note that you may want to keep the passenger side duct open to give the intercooler some cooling air... not sure about yours, but on mine there is a duct that guides the incoming air directly through the intercooler. Actually, it wasn't there when I bought the car used, but I've added it since... I understand that getting the compressed air cooled down helps both power and FE.

1)no problem.
2)same here. lots of weird pockets, exhaust, hitch, nothing to attach anything to.
3)as of this morn, FE was the same as before, pushing 57-63 inst on the flats. will be filling up either today, after i drive 60 miles home, or i might push it and wait till tomorrow, after 120 more miles. i'm at 800 miles for this tank, which is about normal.
4)don't mind at all. would be nice if there was a sub forum just for the MK4 Jetta/Golf/Variants.
i will leave it be for now until the end of the next tank, then i will add/get supplies for the rear skirts and wheel covers and put them on. the 15" wheels will need a 15 3/4" cover that i will tap the lugs for threads to mount them.

I usually don't like to say Subscribed as a post, but I am interested in following this!

When I finish my plan I will be trying a flat rear plate out of the rear.

i know what you mean and i'm guilty too.
i keep up with YOUR post 'cause i am interested too.
my speeds are, to say the least, slow, compared to "normal" drivers on the road. i do pass someone, at least once a month, am able to draft if the traffic is thick enough to create a 'tunnel', i am guilty of hitting my brakes/slowing down when a vehicle gets a little too personal to my rear.

one thing i noticed today after adding the under skirts, IAT reads 105 F now. still not bad considering my latest fuel entry. contemplating deleting the IC to see if there are any differences.

Looking at your picture it appears you do not have the side skirts to you belly pan.
Belly Pan & Sideskirts Underbody Set w/ Hardware (A4) - IDParts.com
I think they help close up the belly pan better.
I would remove the cover over the intercooler also.

i see $229.00 listed for the comolete kit, i don't need the plate.
why remove the IC cover? it's not hurting anything.

They sell just the side skirts too. That was just the full set I posted.

So it can do its job and cool.
I do not know off the top of my head but does the TDI have an intake air temp sensor? If so it would be interesting to know how much covering the IC would affect it.

lots of talk here about warm air intakes.
