What things you do before a SMOG?

:
mazda
California 2013 M5 with 94k miles

Last yr I was charged a SMOG abatement fee - this yr, I will be required to do a SMOG right?

What preparation do u guys do to make it pass SMOG?
Car was well maintained - I am inexperienced with M5 smogs - changing air filter as it was not clean.
Considering using the Redline Fuel system cleaner?

Also do u drive on D2 for 3 miles before the smog to make it warm up?
 
I have owned mine since new
2012 118 k miles

I do nothing special before smog. Drive from my house 2 miles to smog guy

Passes with flying colors

You are overthinking it!

It is not necessary to do a thing.
