Inside their rubber insulation, spark plug wires for Toyota Sienna carry the electrical energy from the ignition to the plugs to trigger the combustion process. A broken or corroded wire interrupts the connection, leading to misfires, rough idle and lower fuel economy. Since the status of the wire isn't obvious from the outside, most experts suggest installing a complete Toyota Sienna replacement spark plug wire set to make sure the problem is fixed. Doing the job yourself saves money, and AutoAnything puts even more of your cash back in your pocket with our 1-Year, Lower Price Guarantee.
