10mm Spark Plug Wire Looms

pinshape

Upgrading from standard factory wiring harnesses to high-performance racing wires is a great move for any VW owner looking to boost their engine's power. Instead of using flimsy zip ties to secure the spark plug wires, why not create your own custom looms that are designed specifically for your vehicle? With a little creativity and some basic modeling skills, you can replicate the factory-style #2, #3, and #4 spark plug wire looms found in most VWs. To get started, simply print out two perimeter shells at 90% infill on a raft, just like the ones shown here.
