Ricepipe + K&N RX-4750, smog test needs a sticker?
I had the most interesting thing happen today. My car dealership was smog testing my Bonneville, and said it passed, except for the intake. They said they would need it to have either: (1) The stock intake, or (2) A "CARB" (California Air Resources Board) sticker with an exemption number on it.
I thought this sounded ridiculous, as last I recalled, the K&N filters and aftermarket intakes were supposed to be legal in all 50 states. So I googled and searched K&N, to find this in their FAQ:
"Typhoon Intake Systems have either been submitted for CARB exemption or they already are CARB exempt. [snip] Our AirCharger intake kits may not be legal in states where under the hood modifications are not allowed. Check your local laws if you are unsure."
I have the Autozone rice pipe with the K&N RX-4750 filter, so I don't even have a K&N intake pipe, and I don't recall the Autozone rice pipe having a sticker. As for the K&N filter, it is one of their "Universal Clamp on Filters" to which they had this to say:
"Universal clamp-on filters may not be legal in states where under the hood modifications are not allowed. Since they can be used on just about anything, it would be impossible to have all the different filters tested for all possible applications. Check your local laws if you are unsure."
My dealer said he'd hold the paperwork on my smog, and if I brought him either my car with factory intake, or a CARB exemption sticker, they would finish and submit my smog test.
I'm a little surprised at all of this. I've never heard of any of our members having any smog certification issues with their Autozone rice pipe + K&N filters before. I figure it'* probably less hassle for me to throw the factory intake on it for a day and get my certification, but has anyone else experienced any problems with "The Man" leaning on them about their intake?

I've heard about people having issues, or maybe I just figured you could, so I've always thrown my stock intakes back on when I was getting an inspection/emissions test. I pass the test and throw the K&N back on.

I take it you're in CA?
Here'* a link to the California Air Resource Board (CARB) approved list of parts in CA:
http://www.arb.ca.gov/msprog/aftermk...rmktdevice.php
Total # of aftermarket engine/intake/exhaust/ignition mods allowed in CA, of any type, for any LeSabre or Bonnevile, of any year, for street-legal use:
Big fat ZERO.
(There is some stuff on the list for certain model years of 3800-powered Camaros/Firebirds and Regals/GP'*, but that'* it)

Thanks guys.
(-and yes, I'm in California.)
I threw the stock intake back on. Busted the IAT taking it out of the K&N, had a buddy get me one from an Autozone. Everything'* back together now, I'll get it signed off tomorrow and throw the K&N back on.
My original IAT had an all-plastic housing, the new one is solid brass. Vastly heftier!

EDIT: change "Big fat ZERO" to "Very near ZERO."

Gut your stock airbox and cut open the front (nothing off the top) so the filter can stick out and get the air, and somehow get the rice pipe to go through your stock accordion tube. This would make an even better CAI, as it would be better shielded from heat, but it wouldn't look as nice, although it may fool the emissions inspector.

at the risk of sounding really stupid..
What'* a rice pipe? And do you really notice that much of a difference with the K&N filter, and how exactly do you "gut" the airbox?
I've read articles here and there about these types of mods, and what I find interesting is some that say the manufacturers have precisely "tuned" the air intake and exhaust to provide the correct amount of breathing the engine needs on both ends to maximize efficiency; in fuel mileage, proper torque in the correct RPM range, and emissions without requiring the cat to clean up unnecessary mess.. I'm not into performance, so my Bonneville resto will be stock, but has anyone seen all that much of a difference, or can prove it, besides saying at the top of the acceleration ramp on the freeway I can now go 73MPH when before I was going 69MPH..
Believe me, I'm not trying to start an argument, you guys have been very helpful to me, but I'm just curious if in the long run you're in better shape.. Thanks.. Mike
