Hello guys,

i searched the forums, but i did not find something consclusive, so here it is:

What cold air intake do you recomend for installing on a '14 991 TT.

I was looking at AWE and maybe agency power, but i inclined more towards the AWE, as they have the inclosed airbox.

I fear that open filters will take hot air from engine bay into the engine, instead of fresh air. Especially standing, and on hot days.

I had this issue with a previous '07 997 TT, wich had the fabspeed intake, and on the dyno, with full de-cat exhaust, and tune, the car was near stock.. intake air was close to 60 degrees celsius.

I admit that the way was measured was not correct , because they did not had ventilators for the side intercoolers.

Anyhow, did anyone has another intake that is happy with it ?

My car so far , has full de-cat iPE exhaust, looking for a intake , and tune, but not powerbox.

Opened to suggestions on that one too.

Do you have video of IPE? I love mine on my C2S.

In modern Porsches, a CAI doesn't help and more often hurts. Have you considered an IPD plenum + BMC filters?

Mufus

I searched months for the perfect exhaust. i think the iPE is fantastic. The car shoots flames, and is loud.
here is the youtube link:

I'm not a turbo but we are the same color too!

Mufus

Nice. there are not many red Porsches out there. Some keep saying its a Ferrari colour
i am thinking about the clear taillights. However, i'm not sure, as they do seem a bit like something from a japanese car

If you're looking for power and performance, the best cold air intake system is what came from the factory.

Cold air intakes = well known snake oil.

Mufus

i somehow agree with this. But on the other hand, i think it needs more air into the engine, and as i intend to do the tune, intercoolers and since i have the free exhaust, i think the intake its important..

If it was only the inake, i would not consider it...

BMC filters will do this and IPD is supposed to be able to aid this. Quality is high - much higher than any CAI. Cold air intakes are mostly for sound so people feel like they are going faster. In old american cars there was ild game but not in something this sophisticated.

i have read on this forum, that a guy was hot very happy with the IPD pleum for the 991 turbo. apparently there are some issues with the part. it does not fit perfectly and you have to strech some vacuum tubes, wich i dont agree also. if i had 997.2 , i would do it with no problem. but in this case... i will stay away. however i am considering the Y pipe. Has anyone fitted one ? makes any difference ? is it worth it ?

This is usually correct.

On some cars, especially those producing high levels of boost, the factory air intake can be a restriction at higher air flow. Back in my R days, some members did manometer testing that showed the factory air box at WOT would be in vacuum. The CAI that was engineered and installed provided a slight ram air effect and created no vacuum pre-filter even on modded cars pushing 25 psi of boost.

Your intake system would best be served with BMC Filters and the IPD Plenum/Y-Pipe. This is the go-to combination (along with bigger intercoolers) being used on the big power builds and record holding 991TTs. For tuning, a COBB Accessport/Protune will absolutely transform the power of the car. Think another 80hp/100tq, it is very impressive.

And what does it do for your warranty and the longevity of the transmission and engine?

Real world question deserves a real world answer I already know the answer to these questions. Perhaps others don't.

Mufus

My car is out of warranty and i dont care about it anyway. These cars are very very resistent. Unless you do something stupid to them, they will last.
And i can afford any damage done to it.

I dont plan going 659468 horsepower. Just a bit more. in the range of 650hp , wich is totally safe for the engine and transmission. However, i will flash the ECU, and not use piggyback devices, as they fool sensors and dont have a correct coordonation between boost, injection timing and other parameters that make a car run correct.

I have seen a 991 turbo with suposedly 700+ hp, and his tailpipes were white like a swedish milf's skin.

Imagine how lean the car runs. Imagine how hot it runs. I would be surprised if it did not melt 2-3 pistons.

So, no, thank you. No piggybacks for me.

There wouldn't be any impact to the transmission.

The engine is debatable but I believe the only risk here is a bad install. You're making air enter the engine with less turbulence and not strapping on 100hp.

John@Fabspeed

All depends on your dealership. Some dealers don't like an aftermarket TPMS sensor, others buy, sell, install, and warranty aftermarket parts and tunes for their clients and have no issues with them doing it themselves. If you have a concern with warranty on your car with any given modification, give your dealer contact a call and work out the details.

I have never heard of any 991TT having a drivetrain failure, they are relatively bulletproof. I have one client in Florida maxing the car out on bigger turbos at about 720whp before the clutch pack started to slip, so he upgraded it and hasn't had an issue since. He was also launching the crap out of that car all day every day lol.
