I remember a few years ago that Casper's Electronics got big fines for selling O2 simulators. All they did was put a big fine on them, and now people order them on ebay. Fucking waste of our tax money prosecuting that crap - it probably cost millions to prosecute them to get a small fine. They will keep making all their stuff, just probably won't do installs anymore.
Buying O2 Sims from a retailer is a thing if the past. Some sellers list them as other parts to get by. Bama or Brenspeed and SCT just got ass hammered by the EPA for tunes.
Probably. CARB busted K&N a few years ago too for selling non-CARB compliant Cold Air kits. I think Cold Air Inductions actually refuses to ship to California because of that BS. It is literally multi-million dollar virtue signaling. There is no societal benefit to prosecuting these people.
