I will be installing a Vortex Rammer air intake on my C5. But first I have two questions: Has anyone taken their C5 in for the California Smog II test with a vortex rammer installed? Does this forum offer a discount anymore on this product?
Unfortunately, the Vortex is illegal in California. The problem too, is that it sticks out like a sore thumb when the smog tech performs the visual inspection. I guess there's always the chance that he'll overlook it (slim, at best), but I wouldn't get my hopes up.
The only two aftermarket intake systems that have the C.A.R.B.-certification are the K&N FIPK and the Granatelli systems. Both are cold air systems.
Obviously, the tech will notice it on the visual and I guess he can fail the car right then and there. The dumb thing about CA smog inspections is that they should be more concerned about the actual smog coming out of the tail pipe and not what the air cleaner housing looks like. The C5 is actually a low emission vehicle according to the window sticker.
Anyone have first hand experience with the actual CA inspection with a Vortex Rammer installed? My car is due for it's 5-year (first) inspection in June. Maybe I should wait to install it so I won't have to reverse the installation for the stupid visual inspection. I guess I should save the original airbox and buy a spare shroud to cut since I will be reversing it every 2 years.
I've never heard or read of anyone driving anything in any state that's been failed because they changed the air-intake or air filter. Seems like the only way an air filter or air-intake assembly is going to cause measurable smog problems is if the filter is so dirty and restrictive that not enough air can get to the engine for complete combustion, causing it to run very rich.

The state simply does not want you to change out anything that has the potential to adversely affect your emissions. I agree that it is rediculous, but I've had smog techs flunk my 68 because it had the factory open-element air cleaner. I even brought my factory service manual with me to prove that everything was legit, but the smog tech told me that I could have "made-up" a fake manual! Believe me, the fines for a smog shop passing a non-C.A.R.B.-certified mod are VERY steep. Why should they take the chance? Can you really blame them?
I read an article years ago about GM computer and emissions controls on the latest cars. Their claim was that cars with modern emissions systems are actually cleaning the air as they drive through LA because the exhaust coming out of the tailpipe is cleaner than the air people are breathing. :D
