New 997.1 TT Tiptronic owner and I just installed these mods:
* Fabspeed X pipe with 200 cells
* Fabspeed Headers
* Fabspeed Competition Air Intake
* Cobb AccessPort (Stage 2 93 octane)


Question: I'm reading online and from other tuners the factory intake is better than fabspeed competition intake because it's sealed to the outside air (not engine bay). The car is running fantastic compared to stock.

Should I really change back to factory air box?

Thanks for your advice!

ask yourself what makes more sense, a design that only pulls in cold outside air or a design that pulls in hot air from the engine bay.

Stock airbox all the way.

But its Fabspeed, less restrictive and its pretty.

Stock....all day every day.

Agree..Factory is best solution.

Fabspeed takes in more hot air than anything. If you feel like the car is quicker with it, it's not. It's the sound it makes.

Best combo is stock air box with drop in filters.

Any airbox that draws in air at a temperature above the ambient available externally will deliver an immediate reduction in horsepower.

The intercoolers will recover a proportion of that (as the now larger difference between the compressed and ambient air temperature will increase heat transfer rate) but you will still be net worse off.

And the warmer the ambient climate that you live in the worse this issue becomes (because the temp difference which drives heat transfer rate is based on Kelvin (or Rankine - i.e absolute zero), not F or C) and so gets proportionally smaller.

Sucking in hot air is only part of the whole negative equation attached to this abomination of a concept. The worst part is using oil filters that are not only at best tertiary in terms of filtration capacity (as in) vs the superior stock filtration system, but are sucking in air from THE most contaminated air stream on offer, being the rear end of the vehicle where the dust ball accumulates and trails the vehicle, swirling under the rear end in and up and around the engine unit. This is precisely why Porsche has designed the 911 air filter intake venting from the lid, being from THE most uncontaminated and coolest air path available on the vehicle. So, with the FS set up they have basically undone all of Porsche's engineering brilliance (at every possible turn) and imposed the worst of the worst of all environmental conditions available, and have you paying handsomely for their cleverness. Marketing at its best! Now. Am I surprised FS calls this a performance upgrade. Nope.

This was on the car when I bought it. It sounded cool and looked neat. But the car felt a bit laggy and when it would rain with the car parked, the filters would get saturated and the car would misfire.

I'm very glad I removed it and went back to stock.

Similar to above, the 997.1TT I purchased already had the Fabspeed intake installed. I'd love to revert back to OEM and will likely do so when I find a reasonable stock setup for sale....

I would stay away from any part with the label "Fabjunk"....
