What is the brown discoloration on the air intake system?
Often it is from chemicals used to help cure the rubber and from UV stabilizers that are mixed in the rubber coming to the surface. These additives are used to help with ozone resistance by coming to the surface and making a "protective" layer. Certain conditions such as elevated underhood temperatures can help to accelerate this issue.

Although quite ugly it is of no harm and can usually be wiped off easily. By using some tire dressing, WD40 or a protectant like 303 it can help the intake look nice longer but typically not stop it all together.

Sometimes you see certain brands of tires that tend to get brown coating on their sidewalls, same thing. Seen it more often on BFGoorich tires over the years personally.

ok, thanks for this info. Elevated underhood temps, a Hellcat would do that.....
