As we continue to take a closer look at some of the details that went into Luft's first-ever build project, focus turned to finishing up the engine and it was decided to forego the stock ignition wires for a set of performance wires by Clewett Engineering.
The set for this 3.2 features 8mm wires with an abrasion, cut and fire resistant protective sleeve. The proprietary spec also includes a spiral core cable for longevity, noise suppression and reliability. So there's no worries of an ignition wire failure when the Luftauto is tearing through the remote back country.
The Clewett set for the Luftauto was installed while the engine was out of the car and you can get a good idea of the protective sleeves for each wire in this shot:
We did an install on an SC engine recently and there are a few features that make the process a breeze.
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.
You can trace each wire individually from the distributor to the plug, freeing thew wire from connectors or mounts along the way.
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 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. 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 the connector (red arrow) to seal the wire to the valve cover surface.
Congratulations! You've just installed a high-quality, heavy duty spark plug wire set on your Porsche's engine. The Luft 3.2 turned out well!
The Luftauto may be jumping creek beds by now, but we're not done! Plenty to come so stay tuned.
