No it didn't, you are making it up in your head. I just read you can't get them in California.

I was joking with you 1troyd! It doesn't come across the same when typing it. The previous posting of them not being shipped to California.

ok cool :-) I had no issues what so ever getting mine ! It really does suck that there is no CARB sticker for it yet !! I mean the Z28 comes with a cone style air intake stock and our Zl1s came with the lame box, looks like a Honda civic to me !! I know they are not the same engine as the Z28, but just saying!!

I already stuck the carb sticker in my engine bay so I will be keeping it. My zl1 is actually a 2015. The k&n said no tune required. While I was at rpm motors I saw a 800 horse zl1 that had a RF installed it just looks like it has better fitment no gap need the strut tower. and a much larger air filter.

well we have a couple of years till we have to worry about smog anyways lol !! so the K&N kit you bought was a 2014 correct ?

I Agree!

I bet the lack of gains was entirely related to atmospheric conditions. You can see that you averaged a fair amount less boost on the 2nd day. That is almost certainly a result of the weather.

I just received a replacement filter for my Roto-Fab shipped to Southern California last week! I guess I need to remove the Roto-Fab and new filter and send it back. If you have bought aftermarket parts, you know they always mark off road use only to escape any legal entrapments.

I thought it was an odd policy too:

That Sucks !!

Something is up because I ran the exact CAI and picked up 20 or more hp over stock a few years ago. Also, the K&N has a larger intact tract compared to other CAI's. It's 4.5" at MAF and 4" at the TB.

love mine

Watch on their website all of their dyno pulls are done with the hood open.

I love the feel of mine also. The car feels more peppy and has a great wine. I just can't understand less power than stock even though it was hotter the second day it was only 10 degrees hotter. I did do two pulls each day one hood open one hood closed. The exhaust sounds much better also now. I guess the true test will be when I install the RF and test again.
