In researching the AIS I find that some say it cools the exhaust and others say it makes it run hotter. Anyone know for sure which it is?
I have no experience with it but I believe it's a form of air injection system that helps burn off any residual fuel molecules in the exhaust to meet tight emmission standards . Apparently it causes alot of the popping when decelerating. I believe only a fuel programmer can help bring down the exhaust temperatures. Some one can correct me if I'm wrong.
