What do the numbers and letters mean on a Champion spark plug?

What do the numbers and letters mean on a Champion spark plug?

The combination of letters and numbers assigned for every Champion spark plug is a logical formula which indicates the major features of its design. [15] Heat Range – The middle number indicates the heat range of the spark plug, the higher the number the hotter the heat range.

Which spark plugs are better copper or platinum?

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 hottest Champion Spark Plug?

Champion plugs are hotter the higher the number, colder the lower the number. Starting with part # RCJ7Y (heat range 7), a colder plug would be # RCJ6Y (heat range 6), a hotter plug would be # RCJ8Y (heat range 8).

What does the Q stand for in Champion spark plugs?

“Q” Type: Uses a wire wound inductive coil (or electromagnetic suppression) to reduce RFI without negatively affecting ignition performance. “Q” type suppressor plugs are specified for most Evinrude and Johnson outboard engines with CDI. “X” Type: Have a special resistor to meet more stringent RFI requirements.

Where are Champion spark plugs manufactured?

Toledo
Champion plants in Toledo produce spark plug shells and assemble the final spark plugs. The Detroit plant manufactures ceramic insulation used in the plug. Champion is a division of Houston-based Cooper Industries Inc., which purchased the company last year.

Are platinum spark plugs worth the money?

If you want a good quality spark plug at a decent price, the platinum spark plug is priced more affordable than the iridium spark plug. The platinum will still last a long time for the money and you don’t have to resort to cheaper copper spark plugs which have a short lifespan.

Do more expensive spark plugs make difference?

This would be more accurately described as “less performance loss.” Spark plugs do not increase the performance of an engine — even spark plug manufacturers are fairly forthright about that. 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.

How do you know if your spark plugs are hotter?

You can work out whether you need a hotter or colder plug by looking at the current ones. If the current plug is too hot then the tip may be melted or deformed. If the plug is too cold then you may have excessive build up (which can also be caused by burning oil or a rich air-fuel mixture).

Will a hotter spark plug stop fouling?

Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean may contribute to pre-ignition or detonation. The higher the compression ratio, the colder the spark plug needs to be.

Which spark plugs are best?

NGK Iridium spark plugs are globally the best performance category of spark plugs having superior technology.

What is the life span of platinum spark plugs?

The design and implementation of these platinum spark plugs is a great advancement which definitely results in improved performance, durability, and cost savings to the consumer. Platinum tipped spark plugs have varying life expectancy ranging from 60,000-100,000 miles.

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

What are applications for Champion spark plugs?

Champion manufactures spark plugs for use in automobiles, high-performance engines, marine vehicles, lawn and garden tools and industrial equipment.
