Complementary Modification:

New plugs

If it is time to replace your spark plug wires I highly recommend that you consider Clewett Engineering High Performance Wires. Clewett wires are on the Luftgekuhlt Build Auto due to their high build and reliability factors. As a matter of fact when it came time to show how to remove the factory wires from a 911 we could not find a Porsche at Pelican that was not already running the Clewett wires.

The wires are manufactured to Clewett's proprietary specifications that include a spiral core cable for longevity, noise suppression and reliability with exterior braiding for increased protection. All wires are designed for procession fit and fitment. The wires are also available in different colors.

The Clewett wires were installed on the Luftgekuhlt Build while the motor was out of the car so this article will show you how to install them on a SC, but the procedures are basically the same for all air cooled 911's

This photo is from the Luftgekuhlt car and you can see that the quality of the Clewett wire was perfect fit for the build car.

Open the engine lid and make sure the car is cold before you start replacing the wires.

The wires are numbered according to each cylinder so it makes it nearly impossible to mix them up.

The wires are numbered according to each cylinder so it makes it nearly impossible to mix them up. If you are just starting to DIY and do not know what the cylinder numbers are begin by replacing one wire at a time starting with the longest wire first.

Look around the engine bay and trace each wire from the distributor to the plug removing any wire connectors or mounts (red arrow).

Hold the end of the connector (red arrow) and twist slightly to break the connection between the connector and spark plug, pulling carefully until the connector comes loose.

Hold the end of the connector (red arrow) and twist slightly to break the connection between the connector and spark plug, pulling carefully until the connector comes loose. Never pull on the wire to remove the connector or use pliers or any other tool to remove them.

The same holds true for removing them from the distributor cap; always grab the connector by the base (red arrow) and never pull by the wire or use some tool to try and remove them.

When installing the connector it is important that you feel and hear the click as the connector has fully engaged the spark plug.
Figure 7

When installing the connector it is important that you feel and hear the click as the connector has fully engaged the spark plug. Due to the design of the 911 motor the plugs are recessed behind the valve covers and some can be difficult to get the connector on the end of the plug; I'm talking to you number 6 cylinder! If this is the first time replacing the wires just take your time and you will get the feel for it. Once the connector is securely on the plug slide the air seal down on the connector (red arrow) to seal everything up.

Remember to reattach all the connectors and mounts on your motor.

Here is another picture of the Clewett's on the Luftgekuhlt car and you can see how the distributor connectors have a 90 degree turn on them but the procedures are the same.
