What does the secondary air do? Compared to a non SAI is it just for
emissions?
Secondary air adds fresh air to the exhaust at startup to help with
emissions until the catalytic converters get up to temp. I’m not sure if
the purpose is to help the cats get up to temp quicker or to help burn off
emissions until the cats get hot, or both.
You guys should do a video of replacing the front main seal on these DII’s
