Flat 6 Motorsports - Vacuum Line Caps (PSE)
Designed to fit:
- 1999 - 2019 Porsche 911 (all models)
- 1999 - Present Porsche Cayman & Boxster (all models)
Note - sold individually, some vehicles require 2 caps. These only work with vacuum actuated valves, some newer Porsche vehicles utilize an electronic valve actuator, please ensure before ordering.
Our custom vacuum line caps are a great way to enhance the sound of your Porsche. Most commonly used on the 718 GT4 that closes the factory valve at random times, these are a simple to install solution that will keep your exhaust valves in a permanently open position.
These caps provide an air tight seal and clean OEM-look.
- Keep exhaust valves opened for louder sound
- Strong & durable
- High-definition 3D printed
- Made in-house in the USA
All you need to do is remove the vacuum line from the valve and insert the block off cap. Make sure the valves are in the open position when performing this step (they should be when the car idled and has been shut off). Due to variances, it may be necessary to remove the small metal clamp to secure the vacuum line block off caps in the vacuum lines. Simply use a pick and wiggle it back and forth to remove. We provide a zip tie to secure it to the vacuum line in case you want to revert back to the OEM configuration at any time.
