IPD Plenum & Y-Pipe Upgrades
An IPD intake plenum and Y-pipe upgrade for the Porsche 991 Turbo and Turbo S (2013-2016), aimed at opening up the 9A1 engine's more restrictive factory intake runners. The aluminum plenum uses a single 74mm throttle body, matched to the factory unit, and IPD's patented design smooths airflow for a broader, more linear power band without needing an ECU flash or triggering a check-engine light. The Y-pipe uses larger, non-round runners with a dimpled interior surface for a claimed 35+ whp and 40+ ft-lbs of torque over stock. Available as the plenum alone, the Y-pipe alone, or both together. Installation is a direct bolt-on, though a throttle body adaptation at a Porsche dealer is recommended afterward for the best result.
Frequently asked
Which cars does the IPD Plenum & Y-Pipe Upgrades fit?
Fits your Porsche 991 Turbo. Fabspeed lists this piece for: Porsche 991 Turbo and Turbo S (2013-2016). Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Do I need to buy both the plenum and Y-pipe?
No, you can choose the Intake Plenum alone, the Y-Pipe alone, or the combined package, depending on your build.
Will this trigger a check engine light or need an ECU flash?
IPD says the plenum should not cause a check engine light or require an ECU flash under normal installation.
Is any extra work needed after installing the plenum?
Fabspeed recommends having a throttle body adaptation performed at a Porsche dealership afterward for the best result, especially if you're also upgrading the throttle body.
Which option should I choose?
The Y-Pipe alone delivers most of the measured power and torque gain and is the more affordable single upgrade. The Plenum alone smooths intake airflow for a broader, more linear power band but is less impactful on its own. The combined Package delivers the fullest gain from both parts together and is the better choice if your budget allows for it.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
