Both intakes are simple to do yourself.
As long as you have knowledge of how to use a wrench/screw driver to remove your bumper, and battery tray as well as the muscle to remove your battery, haha

 

i got all of my windows tinted with the exception of the front window and for all of them the legal va limit it was only 170 with labor

 

im lookin into gettin the windows done on my 99 sedan, and the estimates are all in the $150-$200 range. it costs more with a seamless rear window

 

Mine were $145 cash, no receipt since they are 5%. It's worth going to a tint shop to have it done, unless your experienced it's not easy by any means.

 

i would do the mods yourself.
when i start doing stuff with my audi, ill be doing it myself with help of my moms bf..just so I dont mess up.
He's done brakes for me which cost ~140 to fix [rotars, brake pads etc]...the mechanic at a local shop wanted 1200...
so just do it yourself.

good luck with your car

 

Wow, find yourself a new 'local shop'
