Hi, I recently taken my truck to get it smogged, but it failed while on the dyno. Was told I need a thermostatic air cleaner tube for it, but never heard of that. Looked up online and saw pictures of the tube connecting from the air filter, and thought to myself I already have that. Sure enough I did so I'm trying to figure out what they were saying by thermostatic air cleaner tube. Anyone?
