Thanks for posting that, I'd seen it previously on Bangshift. What's really scary about this is that the EPA's target is the aftermarket manufacturers of parts. Aftermarket parts sources could easily dry up.
Fortunately for us FE guys, we are mostly working on older cars that didn't come with pollution control equipment. But if major aftermarket companies can no longer sell parts for more modern engines, like LS engines for example, it hurts the whole performance industry.
