Does that make them crooks? I won't blame anybody for selling through the vendor that probably has the largest customer base in the market.
Need a reality check on these fog ducts. AMS directly copies other manufacturer's parts. Even if you think these ducts look similar (it's a 3"x5" piece of fiberglass with a hole in it...), these are anything but cast from a mold of a Powertrix or any other duct, and I would like to see you make an argument otherwise.
