Inspection is NJ is free if you take it to state inspection… If you go to a private garage that does state inspection its usually $72… however my street car will never pass because of 5% tint, Emissions, Exhaust noise, adjustable suspension… So i have to pay a private inspection to “pass” my car… usually 150 bucks… But even with a good sticker, i have to dodge the roadside inspections NJ sets up in the summer…
and where the eff is my knock sensor, JEFF?
