Hello -

I got my California smog test in August 2007 :

As stated in another thread, my car passed with great numbers for HC and CO pollution (below the average !), but the NOx was higher than normal. I did have the HAI (Hot Air Intake) online, so maybe this is an effect of the (mild) lean-burn. I think the IAT was running over 125 degrees F when I got the test.

My wife just got her 2003 Civic Coupe tested :

Other than the numbers for the NOx, which are still well within legal limits, my old SW2 is holding up well. My wife's Honda is bone stock, but is also pushing the NOx above average. For each test you can see that the maximum allowed emissions are a wee bit lower across the board. I expected a bigger difference between 1999 and 2003, but I am actually happier that my 4 year older car is being held to close to the same standard. Maybe the maximum emissions is a function of the displacement of the cars. I have a 1.9 liter engine, and she has a 1.7 liter engine.
