High voltage wires (Hyundai Elantra XD)

Incorrect installation and placement of high-voltage wires can lead to spark jumping from wire to wire or to ground, which, in turn, can lead to misfires and a decrease in crankshaft speed when the car is moving at high speed.

Therefore, install the high voltage wires properly as shown in the figures.

Examination

1. Disconnect the high-voltage wires from the spark plugs and ignition coils. Clean and check the integrity of the insulation of high-voltage wires. Check the inner surfaces of the high-voltage wire contacts for corrosion or carbon deposits.

2. Use an ohmmeter to measure the resistance of the high-voltage wires.

High voltage wires
Cylinder	№1	№2	№3	№4
Length, mm	560	440	360	310
Resistance (BOUGI), Ohm	2,51–3,76	1,97–2,96	1,61–2,42	1,39–2,08
Resistance (R16AIPS), Ohm	5,60–11,76	4,40–9,24	3,60–7,56	3,10–6,51

Caution! The resistance of the high-voltage wire should not exceed 10,000 ohms, otherwise replace the wire.
