Hyundai 27501-23B70 Cable Set-Spark Plug

To inspect the spark plug wires on these models, do the following: Inspect the wires individually without mixing up their order, which is crucial for proper engine operation. Number each original wire or use marked tape to identify their locations. Disconnect a wire from a spark plug by twisting and pulling the rubber boot without tugging on the wire itself. Examine the boot for corrosion, and if present, remove it with a wire brush. Push the wire and boot back onto the spark plug end, ensuring a snug fit. Clean the entire wire length with a rag, checking for burns, cracks, or damage, while avoiding sharp bending to prevent conductor breakage.
