I ordered R8 coils and new plugs last night, my car has 96K so i figured its about time. any noticeable difference with these ??

I have also been looking at a tru fit silicone intercooler hose kit with turbo muffler delete. has anybody used this. i already have a high flow intercooler pipe, and silicone turbo inlet. any changes with this ???

Your car is probably running a little more rough than you realize. Plugs should get swapped at 35,000 and 75,000 miles per Audi. So new plugs and coilpacks should make everything run nicer. Some people swear the R8 coils make a difference.... I just put them in over stock because they're red.

my car runs like complete *** and i havent been able to figure out why so im really hoping that helps. plus i get terrible gas mileage

Mine was running like crap at 30,000... plugs and coils helped. You might also want to run a couple cans of BG44K (injector cleaner). Or at that mileage see about getting your injectors ultrasonically cleaned.

EDIT: you might also want to consider carbon build up: B8 A4 2.0 TFSI DIY: Carbon Intake Valve Cleaning

i ran crc 1 step fuel system cleaner, it helped quite a bit

I have already done the carbon cleaning that was a huge mess
