Bosch supplied the world’s first high-voltage ignition system in 1902 and has continued to supply superior wire sets. State-of-the-art manufacturing technology and quality control systems ensure that Bosch Premium Wire Sets meet, and often exceed, the performance of the original equipment wire sets that they replace. That’s true for all of the components, including the wire set boots and connectors.
Bosch provides premium quality, pre-assembled spark plug wire sets for virtually all American, Asian and European cars, vans and light truck applications. And all Bosch Premium Wire Sets are backed by a "no hassle" lifetime guarantee.
