Its great that they do that. Many of these "advertising" threads are fantastic for us when we're shopping around and looking for the parts that are right for our setups. They usually include dyno sheets, video clips (where applicable), and they answer lots of questions. These threads also breed competition within the scene and allows us to discover the latest and greatest stuff that the aftermarket has to offer.
The Market sub-forum is there to sell their wares and get people to actually buy their product once they've done their research.
This thread however (
