Porsche 997.1 RUF TA-style rear bumper diffuser polyurethane (2005-2008)

For an aggressive, tuner-inspired rear, the RUF TA-style rear diffuser is a standout choice. Built for the 2005–2008 997.1 Carrera, it sharpens the rear end and improves underbody airflow.

What is the RUF TA-style diffuser?

It’s a rear bumper diffuser with a RUF-inspired profile that integrates into the lower rear bumper, adding aggressive detailing while smoothing airflow exiting the underbody.

Why polyurethane?

Molded from flexible, crack-resistant polyurethane, it absorbs minor impacts and returns to shape instead of cracking like fiberglass. It arrives ready for scuff, prime, and paint.

Fitment

Fits the Porsche 911 997.1 Carrera (2005–2008). Confirm your rear bumper and exhaust configuration before ordering.

Installation tips

The diffuser uses OEM-style mounting points and includes hardware. DIY installation is achievable; professional fitment ensures the cleanest fit and finish.

Styling and performance

The RUF TA diffuser adds an aggressive, race-bred rear-end look while contributing to underbody airflow management. Pair it with a front lip and side rockers for a complete build.

FAQ

Does it fit my exhaust? Confirm your rear configuration and exhaust before ordering.

Will it crack? Polyurethane flexes and resists cracking under normal driving.
