Distributor cap just like the factory originally installed for your Porsche. Installation requires hand tools and a timing light. Symptoms of a worn distributor are engine misfiring at a high rpm and/or erratic idle.
Complete knob boot units install in seconds: our "vic" line of products avoids the need to glue. Just pop off your emblem and reinstall into new unit. Remove old worn out unit, install new one. That’s it! This part has a 2-3 week lead time.
