Are double platinum spark plugs good?

It yields decent longevity but ranks the poorest in performance. Platinum spark plugs are also recommended for cars with an electronic distributor ignition system, while double platinum spark plugs best fit vehicles with a waste spark distributor ignition system.

How long do Autolite double platinum plugs last?

The answer was double platinum spark plugs, which have a platinum ball welded to both the center and side electrodes. This provides excellent durability with very little gap growth up to 100,000 miles.

What is the difference between platinum and double platinum spark plugs?

A single platinum plug is much like a copper spark plug with a platinum disc welded to the center electrode; a double platinum spark plug has a platinum disc on both the center and side electrodes.

Do Autolite double platinum spark plugs need gap?

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.

Should I change spark plugs at 100000 miles?

If you buy a new or late-model used car, chances are you’ll change vehicles before you need to change the spark plugs. How long spark plugs last varies by manufacturer and vehicle, but on many vehicles today, they should be good for 100,000 or more miles.

What are double platinum spark plugs used for?

Double platinum spark plugs were designed for “waste spark” DIS. In a waste spark system, the spark jumps from the center electrode to the side electrode for the cylinder that’s on the compression stroke.

Do Autolite iridium spark plugs need gap?

In most cases your Iridium Power plugs do not need to be gapped. Should you decide to re-gap your Iridium Power plug, use extreme caution as improper gapping may damage or destroy the Iridium center electrode or porcelain center.

Are platinum plugs better than copper?

Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. Platinum has good longevity and the worst performance.

What is the best platinum spark plug?

For the vast majority of drivers on the road today, the Bosch Platinum +4 can be considered the best all-around spark plug. The Platinum +4 achieves its high performance by employing four (as opposed to one) yttrium-enhanced ground electrodes.

What is the best spark plug for performance?

Four Different types of spark plugs: Iridium – Often considered to be the best spark plugs for high performance and longevity. Iridium usually lasts 25% longer than platinum, but you guessed it, they’re usually more expensive! Platinum – An upgrade from Copper plugs that can last up to 100,000 miles of usage.

What is the best iridium spark plug?

Why it’s best: Iridium spark plugs may offer the best performance outright of any type of spark plug available, but the drawback is the high initial cost. To remedy this shortcoming, Bosch offers the Platinum IR Fusion spark plug.

What are the benefits of double platinum spark plugs?

– Platinum-to-platinum firing for superior durability – Super conductive Yttrium enhanced ground electrode provides superior heat transfer – Platinum enhanced high nickel alloy side electrode maintains precision gap – Platinum tip assures virtually no gap erosion for longer plug life – Maintains optimum performance and fuel economy longer – 5-year limited warranty
