Frequently Asked Questions
Does the Akrapovic DI-PO/CA/8/G fit the Porsche 718 Cayman GT4 RS?Yes. The DI-PO/CA/8/G is compatible with the 2020-2023 Porsche 718 Cayman GT4 and GT4 RS, as well as the 718 Spyder and Spyder RS, as all share the same rear body architecture.
Is this a carbon-wrapped OEM diffuser or a completely new piece?The DI-PO/CA/8/G is a completely new design, not a carbon-veneered factory component. Akrapovic developed an entirely new aerodynamic form that replaces the OEM diffuser and gives the rear of the 718 a more aggressive, motorsport-influenced appearance.
Will the DI-PO/CA/8/G fit my 718 Cayman GTS 4.0 or 718 Boxster GTS 4.0?The DI-PO/CA/8/G is specifically designed for the GT4 and Spyder models. Akrapovic offers a separate diffuser SKU for the GTS 4.0 models (DI-PO/CA/8/G/1). Please verify your specific variant before ordering.
What finish options are available for this Akrapovic 718 diffuser?Akrapovic offers this diffuser in high gloss (DI-PO/CA/8/G) and matte (DI-PO/CA/8/M) finishes. Both share the same carbon construction and fitment. The high gloss variant features a UV-resistant clear coat for a mirror-like appearance.
Can I install the DI-PO/CA/8/G without professional help?The diffuser uses OEM mounting points and is a direct bolt-on replacement, making it installable by a mechanically capable owner. Professional installation is recommended to ensure correct panel gap alignment and to avoid potential stress on the carbon panel during fitting.
What is the weight of the DI-PO/CA/8/G compared to the OEM diffuser?The Akrapovic DI-PO/CA/8/G weighs approximately 1.9 kg, which is significantly lighter than the factory plastic diffuser, contributing to a small but meaningful reduction in total vehicle weight.
Does this diffuser require any modification to the rear bumper or body?No modifications are required. The DI-PO/CA/8/G is engineered to mount directly to all existing OEM attachment points on the 718 GT4 and Spyder without drilling, cutting, or adapters.
How do I maintain the high gloss finish on the Akrapovic carbon diffuser?Wash with a pH-neutral automotive shampoo and dry thoroughly to prevent water spots. Applying a UV-protective ceramic coating or quality car wax two to three times per year will extend the gloss and protect the clear coat from UV degradation.
What warranty does Akrapovic offer on the DI-PO/CA/8/G?Akrapovic backs the DI-PO/CA/8/G with a 2-year manufacturer warranty covering defects in materials and workmanship when the product is installed and used as directed.
Installation Instructions
- Safely raise and support the rear of the vehicle on a lift or jack stands to provide access to the underside of the rear bumper.
- Locate and remove all retaining clips, bolts, and push-pin fasteners securing the factory rear diffuser to the bumper and body structure.
- Carefully detach and set aside the OEM diffuser.
- Test-fit the Akrapovic DI-PO/CA/8/G to confirm all mounting holes align correctly before applying any fasteners.
- Install the supplied mounting hardware and begin hand-tightening all fasteners from the center outward.
- Torque all fasteners to specification and verify even panel gaps across the full width of the diffuser.
- Lower the vehicle and conduct a final visual inspection from the rear to confirm symmetry and alignment.
