FAA-PMA approved Slick Harnesses by Champion are built to handle the maximum spark energy produced, while delivering more energy than is required by the spark plugs - even during emergency full-power engine operation. Using anything less could result in more than a 50% reduction of radio sensitivity in commonly used communication frequencies, as tested by Champion. Features such as a heavy-gauge contact spring provide more contact area and force inside the spark plug, while the flexibility of the coiled center conductor reduces fatigue and breakage resulting from repeated temperature cycling and vibration.

The product looks good only it was gray instead of red like I ordered
SLICK HARNESS M4001R RED
Replaced my aging and deteriorating harness on my O-320. Replacement was simple. My engine seemingly has more power and runs considerably smoother. Great investment.
