The automotive speed technologies 996 tt fresh air intake plenum and hard inlet pipe kit is designed to enhance the performance of your Porsche 996 tt by allowing fresh air to flow freely to the turbos for quick spool and additional power - very important for modified cars running larger than OEM turbos or running high boost. The system consists of the speedtech hi-flow intake plenum with 70mm outlet tubes, attached to 70mm molded hard plastic tubes for uniform high flow. Silicon hose is supplied to connect to the turbo inlets. The speedtech hi-flow plenum is designed to flow more air than the OEM plenum and deliver it quickly and smoothly with no restrictions from the maf tube all the way to the turbo inlets. A very worthwhile and important upgrade to maximize power for all modified 996 tts.


Speedtech design advantages:

The lower plastic pipe is 1/4 thick and extremely durable - virtually indestructible. When a plenum and fresh air inlet pipes are installed, these pipes are sandwiched between the motor and the firewall and are exposed to a lot of vibration and chafing. They are also open to the underside of the car. A breach of this pipe at any point, whether from rubbing behind the motor or road debris from underneath the car will result in dust, sand and/or stone being sucked in to your turbos and motor. Since these areas are seldom checked, if ever, a failure will most likely result in unknowingly sucking debris into your motor for an extended period of time or until it causes a catastrophic failure.

Speedtech firmly believes that this is not an area to take a chance with less durable materials such as some of the hose designs or any other thin walled materials which are susceptible to wear, puncture or both. Their piping is considerably thicker than the OEM plastic pipe it replaces, which makes this a significant upgrade in terms of quality, durability and performance. This product offers high, unrestricted air flow, a very uniform and smooth air passage with no abrupt angles or necked down transitions and extremely durable piping behind and under the motor, where it is vital for long term reliability and complete peace of mind.

The speedtech hi flow plenum is available in a variety of extremely durable powder coat finishes and can be matched to your car exterior color or any other color you desire for a beautiful show car appearance. This is an exceptionally well designed, high quality upgrade for your Porsche 996 tt.
