    Like I said a lot depends on how you use the car, your particular location, your particular car itself, your other mods, and which intake you use. There is no absolute answer to this question.

    And that would be exactly opposite of the truth.

    Im glad you can bring your infinite knowledge to the discussion. I don't particularly care if the intake does much for the car or not. There are quite a few people who would disagree with you... and while im not some huge perrin fan I think they know more about their own intakes than yourself. Crazy thought I guess though huh?

    Trust whoever you want. Obviously Perrin speaks the absolute truth with their claimed HP/TQ gains with the intake so you should just rely on that and ignore everything everybody here says.

    Don't come asking for advice and then bash very experienced, knowledgeable members. The cars in my signature have more money in mods than you've ever spent on cars in your life.

    Adios.

    It may seem like a silly question, and I'm actually pretty sure I know the answer, but here goes: Why would you install the intake if it has no performance benefit and may even hurt performance and/or cause damage to your new car?

    My read on that information from Perrin would be that it does skew your MAF scaling. The stock tune is conservative enough probably being rich (I assume they are like the old models were notorious for) to be "safe" in their opinion. I.e. it isn't right. Then the error is too much for a leaner tune with more boost and maybe more timing.

    This is a circular argument. You are saying they do have a large benefit, but you don't believe Perrin because they say it is a large benefit.

Technically the older models don't require a tune to run with an intake either, but the answer to the question varies a lot in terms of the particular intake, your location (i.e. altitude), and what you use the car for/how you drive it.
    The particular intake, yes. I don't see how those other elements factor in though. About it being technically OK in general on older models - that is a big no.

    Adios.
    He wasn't asking for advise - he was offering it. I'm not going to weigh in on the HP argument, but I think there are two sides to that story. As far as the only thing asked, will it harm the car, he agreed with you then you called him out for it? Maybe experienced members could use sound logic and actual information to make a point instead of pulling trump cards on newbs? Do you actually have any experience with that intake and what it does to A/F?

    The stock ECU can scale for increased air flow but only so much. As long as the MAF sensor is getting a nice clean reading of the air flow. If the airflow is too much the ECU mapping won't have enough range to adapt and then you go lean.

    Though advertised power numbers can always be scewed (<- don't think i spelled that right haha), every dyno is different and every car is different.

    However - a company would not last very long if every part it sold blew up someone's car. They'd quickly lose sales. I'm not sure how many intakes Perrin has sold but I've not read or found one person stating their car blew up or ran dangerously lean from running their intake. So for them to say it is safe, they would have needed to test 'multiple' cars in at different elevations to confirm the stock mapping can adapt without running lean or throwing a code. Plus get CARB approval in all 50 states.

    So the ultimate question is: Is it ok to run the intake without a tune? - I say you will be fine.

    Will you gain more power with a tune and intake? - Definitely.

    The Perrin intake is CARB approved?

    I'm under that assumption - no one take that as gospel.

    I would not make that assumption. I would also not assume it takes any testing whatsoever for them to say "it's safe."

    I read up on their website that the intake is 'off road' only so it is not carb approved. What i said still applies though.
