What are Autolite spark plugs gapped at?

Autolite doesn't recommend adjusting the plug gap more than . 008" in either direction. Beyond that slight adjustment, the ground electrode and center electrode won't align properly, hindering spark plug performance and drastically reducing plug life. via

Do you gap autolite racing spark plugs?

Even though many spark plugs come pre-gapped, that spark plug has had a long trip to your garage. Below is a picture of a common wire gap gauge. This is our preferred style because when used properly you will not cause any damage to the spark plug. via

What is the usually range of spark plug gap?

Spark plugs in automobiles generally have a gap between 0.6 and 1.8 mm (0.024 and 0.071 in). The gap may require adjustment from the out-of-the-box gap. A spark plug gap gauge is a disc with a sloping edge, or with round wires of precise diameters, and is used to measure the gap. via

Do you gap Autolite platinum spark plugs?

Autolite spark plugs traditionally leave the factory pre-gapped for their most popular application. However, a plug may fit hundreds of engines, from cars to golf carts. Gapping the plugs to your engine's specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy. via

How long do Autolite platinum plugs last?

Platinum Spark Plugs

Provides a center wire platinum firing tip. Benefits include: reduced gap erosion, fewer misfires, better performance and more durability. Guaranteed for four years. via

Are Iridium plugs pre gapped?

Iridium Power Gapping Tips

In most cases your Iridium Power plugs do not need to be gapped. Even with small variations in the factory set gap the ultra-efficient firing power design will compensate for those small variations. via

Which autolite plug is hotter?

Autolite indicates the heat range with the last digit of the part number. For example, 3923 has a heat range of 3. The higher the number, the hotter the plug. The lower the number, the colder the plug. via

What happens if a spark plug gap is too big?

The customer may experience loss of power, misfires, spark plug fouling, increased plug wear, or poor gas mileage. Too small of a gap may give too weak of a spark to complete the combustion process within the engine; too wide of a gap can lead to the spark plug not firing correctly, causing misfires at high speeds. via

Can WD-40 clean spark plugs?

WD-40 removes carbon residue and keeps moisture away from spark plugs and spark plug wires. WD stands for Water Displacement, so if your spark plugs are wet or you need to drive moisture away from ignition distributors, WD-40 will do the trick. via

Can I spray WD-40 in spark plug hole?

Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion. via

Is iridium better than platinum?

Iridium is said to be six times harder and eight times stronger than platinum with a 700┬░ higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. via

Do more expensive spark plugs make difference?

They won't make the engine perform better than it did when it was new, but they will help it stay at that level longer. Are noble metal plugs worth it? That's up to you. If you want long-lasting plugs that will reduce the work you need to do replacing plugs and don't mind paying extra for that luxury, yes. via
