What do illegal car parts effect in terms of your insurance/ smog check/ DMV?

was thinking about letting my friend build me a custom cold air intake and him installing it into my car. If i were to do this im pretty sure that i would have to replace it every smog check, but how will it affect my insurance if i were to get into an accident with it? What other things should i know if i were to drive with illegal car parts in terms of other mechanics fixing it or just other info...





Thanks.|||No, there is no smog device before the metering device, and that is all he would or could replace. Nor is any device illegal. Modifications are all legal, as long as you pass DEQ, and you can always apply for a variance even if you do not pass, as custom and race cars often do.


Nor does the insurance company have any authority to know anything at all about it.


Have the world modifies their engines somehow, with chips, cold air intakes, and even turbo chargers.


If Ferrari can sell new cars with all this stuff and all that horsepower, you can do it to your car as well. It is not illegal until they start making Ferraris illegal.


Are they going to fail you if you put a Ferrari engine into your car?


I don't think so.





What DEQ will check is whether or not you are illegally diverting exhaust around the tailpipe, where they are trying to check it.





But if you live in California, you should probably check their laws in more detail, because they do lots of things that don't make sense and are not really legal. That is because they claim no one needs to be able to drive.
