I really don't see much of an aftermarket in the near future. When you consider research, start up costs, production costs vs the size of the market, it's probably cost prohibitive. Down the road though, once the GTDI class of engines takes a firm hold, I can see a strong aftermarket there. We're at the dawning of a new era here. Ford has a 2.0 GTDI engine in the works. You also have to take into account that the auto makers are currently hanging on by the skin of the teeth. R&D is on the back burner. All we can do is sit back and see.
