I was thinking of getting a better ...breather for my 997.1 TT.
The engine is stock but flashed.
One product is Agency Power Carbon Cold Air Intake and the other is Maxflo.
Does anyone have tried any of these?
Does anyone have a DIY ideas?
I think that both are pricey...
and what about the Muf sensor?
Thank you guys for listening!

 

save your money. the stock unit is very good.

 

Nope.

Imo, a better use of your money would probably be GT2 RS intercoolers.

 

The stock unit is the best air intake up to about 1,000 hp, It has a venturi effect that the cold air intakes do not have and the best part is that it does not suck in the hot air from around the engine. There has been some engines with internal rings/pistons burning because of the hot air getting sucked in.

Keep it stock!

 

Good advice.

 

should I change the filter at least to BMC or keep it stock as well?

 

I believe that the BMC filter is also a gadget that is not worth the money. I could be wrong, but it may do more harm than good.

 

This aint a F150 or a Mustang that will benefit from a K&N Air Intake. Porsche did their homework.

 

NO, and NO on the Bmc as well

 

You will have problems with your Muf sensors...

 

Better flowing exhaust and bigger intercoolers is where you will get more bang for your buck

 

^This.

 

We do see a worthwhile improvement with the BMC filter (especially if your OEM filter is old/dirty), but as others have said I would skip the full intake box.
