Version 3 Engine Baffle Ignition Wire Seal - Two Wire
 
Lycoming, Continental, and others
 
A part to pass spark plugs wires through the engine cooling air baffle.  This part has the exact same mounting hole spacing as the Slick version.   Uses #8 washer head screws (included).  Max temperature = 300 Fahrenheit.  
 
A drill jig is recommended for drilling the holes to mount the seal because the holes have a line fit.  Using the seal as a drill jig may oversize the holes and reduce the tight clearance fit.  A free drill jig will be included with the purchase of two assemblies in order to complete the installation for the engine. 
 
Note: These are priced and sold per assembly.  Each assembly contains 2 pieces.  The item will ship exactly as pictured.
