I have just about come to this conclusion as well. I mean the stock air intake setup is already pulling air from outside the engine bay.

So now I have been trying to decide what aftermarket filter to pick up. K&N is usually a go to. Do you have a preferred one?

K&N seems really popular. A bunch of people were excited about the Works filter for a while as it was marketed to have the highest gains. I think Zeta and Perrin have options you can look at as well. I'll bet they will all perform about the same. Just pick what you like.

Pretty sure that Toyota marketing bro just threw a number out...

Overpipe back exhaust with catless downpipe should easily be good for those claimed power gains. Will be interesting to see when people start getting these if they do much or not. I do like the fact it cleanly removes the main resonator without having to cap it off or modify the stock box. Plus the filter can be cleaned without removing the bumper.

Do tell us your vast experience and the knowledge on the subject.

So the exhaust is not big enough and the intake it too big? Got it. I'm going to have to forget everything I know and have a conversation with you. School is in progress. Let me go get my pencil and paper. :cry:

dont quote me on this but what i know running a high octane does not mean you will gain more HP especially without a more aggressive timed tune, actually a lower octane provides a stronger spark hence a stronger bang. The higher the octane the cooler the bang which helps reduce knocking and detention risks especially with boosted motors.

please correct me if I'm wrong ! i don't mind getting educated about this too !

Feel free to pay $1200 for a catback exhaust that does nothing but sound, and an intake that's a larger version of the stock one that removes the snorkel for a higher price than the Perrin + inlet or a way higher price than the FA20club CAI. $425 for a plastic box with red TRD letters glued to it? LOL. Filter is still inside the hood, just like 90% of the other intakes. The aFe pulls from the same scoop.

$1200 just about gets you a full headerback from Perrin or a downpipe/axleback combo from Nameless. Makes zero sense.

They did make more power out of their supercharger than Innovate did...trustworthy

Does it remove the snorkel. I was under the impression it used the stock snorkel. Do you mean sound generator?

I was actually talking about the inlet tube where the stock sits and pulls the air. Guess I should have said fresh air scoop.

High octane increase the flash point and keep the engine from detonating. All it's doing it keeping the knock sensors from backing out the timing.

Explain why having the filter inside the engine compartment matters when the air is drawn from the exact same place as the Perrin intake, in front of the radiator. I just find it interesting that people seem to think a 122 cubic inch, 200 HP motor needs to flow air like a big block V8....

Heat builds up under the hood from the engine, therefore raising intake temperatures. Just look at the Injen intake thread where they dyno'd it open hood vs closed hood. Massive difference.
