"Our fun old vehicles have spark plug wires that go bad over time, but our new daily drivers have no spark plug wires and their ignition systems are maintenance free." True or False?

"Half-True" is the right answer! Most newer engines do not have spark plug wires, but they do have Spark Plug (Coil-On-Plug) Boots. A spark plug boot connects each spark plug to its individual ignition coil. Boots are often overlooked because they are out of sight. Like spark plug wires, these boots do age and may suffer internal damage from high-voltage electricity or cracking from engine heat.

RockAuto carries a wide selection of high quality brands, including boots by Standard Motor Products (SMP), ACDelco and Motorcraft, for vehicles ranging from 1990 to 2016. We also offer Ultra-Power Spark Plug (Coil-On-Plug) Boots, produced at the exact same factories as the famous brand name equivalents and with prices that can save you 10% or more compared to RockAuto's other reliably low priced parts.

Spark Plug (Coil-On-Plug) Boots are relatively easy and inexpensive to replace. You can find Spark Plug (Coil-On-Plug) Boots (along with other classic tune-up parts for older vehicles) listed under "Ignition" in the RockAuto catalog.
