    I don't know where you took reading comprehension, but your quoted section makes ZERO mention of any model below '08+.


    I'll put this nicely...you are wrong, and please stop posting misinformation.

    Sorry according to cobb your wrong again..

    No Tuning Required
    This COBB SF Intake does not require additional tuning once installed. It is designed to work perfectly with the stock MAF sensor. Simply install and go!

    Do not require any form of tune for intakes.

    I can assure you, my statement is NOT wrong. There has got to be some kind of disconnect in the communication here...

    According to Cobb, THEIR intake on the '02-'07 WRX/STI does not require MAF scaling. Their tolerance levels are more lenient than mine in terms of vehicles I tune (which, for their purposes, they have to keep things lenient considering all the conditions they have to deal with). I don't say that if +/- 1PSI of target boost, the tune is good. I don't say that if 8% AFR Learning, the tune is good.

    Cobb intake may be "safe" with the stock MAF scaling on pre-08 vehicles, but if someone were to interpret your comment to mean that any stock-sized intake is "safe" without MAF rescaling (hence the outcry), that could spell disaster for them.

    Only an 08 up would require a tune ...

    As stated if your car is an 08+ that's where they say you need a tune according to say COBB.. Before 08 there is 0 tune required for an intake..
    This may be semantics, but if you are only referring to Cobb's intake, then all those times you said "an intake" or "intakes" that I just quoted...you probably should have said "Cobb's intake" instead. Again, may be just semantics, but someone could read those and think that you, and by your reference Cobb, are generalizing. You have not been as specific or clear as you claim you have.

    So, guys I am not trying to stir the pot here. I agree with you guys 100%. I actually removed the perrin CAI from my car yesterday and put the stock intake system back on until the rest of my parts arrive at tax time. But this is directly from PERRIN's website.......

    ***Stock ECUs-PERRIN Intakes will run safely with all stock cars, running stock ECUs. No modifications are required.***

    Just blows my mind that they would make such a broad statement without there being truth to it. Now I know perrin is not the only company that makes this sales pitch. Injen and I'm sure others claim this too. Just makes me wonder. Oh well, I am playing it safe. No more CAI until I am stage 2.

    I'm sure they have done a ton of research to make sure they can put that claim out there. Most likely your car will not explode by putting the CAI on, but if you don't have any way of being sure then do you really feel safe slapping the intake on? I might feel safer with the statement from Perrin if they guaranteed they would replace my engine if anything went wrong with it after installing the intake. But they don't. Thing is, if you don't have any data logging/monitoring capabilities then there would be no way that you could prove for certain that the intake was the cause of a destructive event (and probably would have a hard time proving it with data logging/monitoring too), and thus couldn't really go after Perrin for making the claim they make. Most likely that is why they feel safe putting the statement out there.

    Don't get me wrong, I like Perrin products (I have their CAI and a stage 2 tune from them.) They also have very good customer service. But I do monitor the engine constantly rather than taking Perrin's word that everything will be ok.

    I agree. I think Perrin is a great company. I have been buying parts from Perrin since my first wrx and have had nothing but good things to say about them. I understand completely what you are saying. I will not run my CAI until I am stage 2 with a AFR gauge to monitor it correctly. Just for the peace of mind, don't want my engine to go boom before I even start my build lol!

    Every single quote you listed had Cobb in it. So yea that was implied. But I see what your saying its semantics?
    Sorry for any confusion there
