Full Emissions hotwire auto hemi wiring harness

The cutoff is 1975 thus if your car is a 75 model year or and earlier you are not required to have the biennial inspection. There was a bill before the legislature to raise it to 1980 but it died in committee.

I too have never heard of anyone with a pre '75 car being forced to have an inspection. That being said, beginning in '65 cars in California had rudimentary smog control devices, and removing them is both a state and federal law violation. It is a civil law, not criminal law though.

Smog laws do follow the motor so technically if you install a 2006 Hemi in a '65 Cuda you are technically required to keep and install all of the emission control devices. The irony is that by making it near impossible to install a late model motor in an earlier model car the government in effect causes more pollution.

For example, a late model computer controlled motor even without cats will be a lot cleaner than a 60s era motor with a carb.
