I have a fab speed one
along with a BMC F-1 filter.
I installed them about 4k
miles ago and to date no problems.
The car seemed to have a marginal improvment
in throttle response in the low and mid range
and all though its louder at the higher rpm range
I didn't notice any power gain up there.
I'm coming up on 10k miles and previous posts
have stated that the engines seem to loosen up
or get quicker around the 10k mark. Fortunatley
that seems to be true. I don't have another brand
to compare the fab speed too but if I had to do it
all over again I would start with the BMC filter and
go from there.

The stock system is cold air. The intake horn on the left side of the deck lid collects through the vent slats and funnels into the air cleaner element.
Two aftermarket systems, both improving flow are available at this time. Fabspeed furnishes an upgraded intake pipe, blocks off the helmholtz resonator and provides an improved filter element. Evo replaces the airbox and changes the filter element. Both improve air flow, with the Fabspeed about 15 % and the Evo about 30%, supposedly. Rear wheel horsepower gains are 5 hp, maximum.
The factory X-51 powerkit intake has a modified deck lid, carbon fiber airbox, two intake horns, a larger throttle body and improved intake manifolds. Parts are probably unavailable and priced in the stratosphere. Including the widely discussed PSE, 26 horsepower is claimed. Actual power may be higher.
Manthey Motors and PSI(both not well known here) have complete, high priced engine tuning systems claiming 400 hp for the 997S.
This is where we are. Good luck.

Are you speaking of the X51 Air intake which is carbon fiber? That alone would generate 26hp? I have Tubi headers and tubi exhaust, would this be the unit I need?
I have purchased but will return the new k&N cold air intake offered by vivid racing. I just put it on today, however I am getting MAF errors, although there is a remarkable increase in power from 3000rpm and up, it screams to redline.
Should there be further recalibrations to not redline so quickly?

Hey Jay, who did your Evo? Farbacherloles?
Maybe one day I may take the plung
Man did I have a crappy day... I ripped the passenger lower lip of the Aero today, but snapped it back in. The Armorglove took the most of it. I had Charlie order a GT3 lip as it's a matte finish and my original comes primed only and would have to be shot.
You'd think Porsche would offer a cold air aftermart kit. I can see the cost now!
Any change in sounds? I may have to meet up and listen to this beast you unleashed!
Regards,
Deanski

Deanski, Danbury Porsche did my Evo install. They a great job and at least new it was covered under warranty. As a matter of fact on part was incorrect. They called Evo for me, had the part Fed Exed over night and Paragon, whom I purchased the part from, gave me instant credit. A great experience all around.

That's why I find it so hard to believe "tuners" who state 5-10hp gains for a airbox, etc. Royalpar... for nearly $17k, Porsche engineers can get you 26hp (and of course, an engine that revs much, much more freely).
The X51 powerkit installation also lifts the redline to 7,600.
BTW, that $17k number is for X51 as a factory installation... not sure what the dealers are charging, but the TSB for the install is about 12 pages long and references many other documents...
Personally, I'm holding out for a slightly used 997 GT3 in a couple of years. I drove a buddy's 2004 GT3 MK.II and was VERY impressed.

Have a good day!

26 hp for 17k just sounds high - wouldnt it be cheaper for porsche to just drop a 4liter engine back there? 3.6l to 3.8 gives you 30...i cant imagine a 4 liter engine costing more than 17k over a 3.8l
