Autolite

Autolite is a spark plug and ignition brand found in many American garages. At Restauco this page brings together Autolite spark plugs in several types, plus diesel glow plugs.

On this page you will find Autolite Copper spark plugs, Autolite Platinum and Double Platinum spark plugs, and Autolite Iridium XP spark plugs, which use an iridium-enhanced fine-wire center electrode and a platinum ground electrode. For diesel engines we list Autolite glow plugs, which heat the combustion chamber for cold starts.

From the shop: use the plug type and heat range your engine calls for. Moving to a different plug type is not always an upgrade, and the wrong one can cause misfires. Check the gap before installing, but be careful with fine-wire and precious-metal plugs; never pry on the center electrode. Install plugs by hand first to avoid cross-threading, especially in aluminum heads, and torque them to spec. Look at the old plugs when they come out: oil, carbon or white deposits tell you how the engine is running. On diesels, a hard start in cold weather often points to glow plugs or their relay.

Confirm your plug by the number on your old plug, or by year, make, model and engine. Send us your VIN if you need help.
