Jerry, any chance you know the part # for this kit and if it was C.A.R.B. approved? The smog guy would not test me because I did not have a CARB approved air filter and tube. I realize they aren’t the best. Just trying to find the packaging that will fit my current set up in order to pass.
That TurboCity Rock-It Tube kit was (https://ww3.arb.ca.gov/msprog/aftermkt/devices/eo/d-470.pdf) but they're not in business anymore.
