Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm selling my IPD Y-plenum. It is an easy bolt on install behind the throttle body. This is for cars with cable throttle (not E-gas).
$400 including free USPS priority shipping to USA (please ask about other methods/destinations).
Retails for $900.
Payment via paypal.
I'm not sure about the HP claims below, but if you have other intake or exhaust mods, this will compliment them well.

Porsche introduced all 996 C2's with conventional cable throttles while all C4's were equipped with E-gas throttles. This was for the model year 98 in Europe and 99 in the US.
The IPD "Y" designed Cable plenum is a direct factory replacement of the OE "T" style air distributor. The IPD Plenum provides impressive max horsepower gains of 28 in the mid range and an additional 12 horsepower on top.
The IPD Plenum is the absolute single best modification that can be installed on these early under powered 996 Carreras and will transform your Porsche driving experience.
Installation is relatively easy and straight forward for mechanically inclined DIY customers although IPD strongly recommends having a qualified Porsche technician perform any IPD Plenum installation.
To confirm whether your Porsche is a Cable or E-gas throttle simply look at your throttle body for either a black electronic module (E-Gas) or a conventional spring / cable throttle control.
Tardy to the party (again).... Let me know if your sale falls thru and I'll buy it. I have FVD's slightly larger TB and I'd love to dyno before and after just to see if they're full of bleep....
I haven't dyno'd it since I installed it but there's definitely more pull across the power band. How much more I haven't a clue. Unfortunately I probably won't dyno the car again until September but I'll post numbers then....
