Porsche Mileage Blocker Installation Service

Protect your Porsche’s odometer accuracy during dyno testing, track days, or off-road use with our professional mileage blocker installation service in Slough. Our specialists have extensive experience with Porsche 911, Cayman, Panamera, and other high-performance models, ensuring a safe and reliable installation tailored to your vehicle.

A mileage blocker allows your Porsche to record precise performance data without adding unnecessary miles to the odometer. These devices are designed for off-road and testing purposes, and while we provide professional installation, we cannot guarantee they are undetectable.

Our Slough workshop provides expert guidance and model-specific installation, ensuring your Porsche remains fully functional and safe while the mileage blocker is in use. We combine precision engineering with local knowledge, delivering a service that Porsche owners in Slough can trust.
