Here is a great video to help you determine what spark plug is best for your application.... read more



Video Transcript

How do I choose the right spark plug? When choosing a spark plug, there are some things to consider if the applications has not been modified then referencing the NGK part finder or printed catalog will suffice. If the application has been modified, then there are other factors to consider: thread diameter, thread reach, gasket or tapered seat, heat range, projection and electrode material will all need to be taken into consideration.

Modification such as the addition nitrous oxide, forced induction or modified compression ratio will require an alternative spark plug selection.

Changing spark plugs Performance Improvement Video

Changing spark plugs Performance Improvement NGK Spark Plugs Tech Video

Here is a great video on answering the question about how much preformance improvement can I get from using better spark plugs.... read more



Video Transcript

How much of a performance improvement can I expect from changing spark plugs? Installing new spark plugs will not increase total engine output. Replacing worn spark plugs will only result in the smallest power gains typically about 1 or 2 % of total engine output. Modern vehicles that are computer controlled may not even see the 1 or 2 % increase as a feature more powerful ignition in systems that can compensate for the power loss of this minimal percentage.

The most important thing that changes when new spark plugs are installed is overall engine efficiency.

Gap Opening & Closing

Spark Plug Gap Opening & Closing

Here is a great video that talks about the gap opening and closing.... read more



Video Transcript

What is the maximum I can open or close the gap? A spark plug should not be open or closed more than eight thousands of an inch (.008”) from the original gap size out of the box. For example, NGK TR5 will come out of the box set at forty thousand of an inch (.040’). The widest we can open the gap is forty eight thousands of an inch (.048”), the narrowest we can close the gap is thirty two thousands of an inch (.032”). Adjusting the gap beyond this will result in poor performance due to misaligned electrodes and cause increased stress on the ground electrode as well that could lead to failure.

Spark Plug Numbers & Letters

NGK Spark Plug Numbers & Letters: What Do They Mean? (video) Video

Here is a great video that describes what the letters and numbers for a spark plug indicate.... read more



Video Transcript

What do the numbers and letters in a part number represent? Each part number is made up of a combination of letters and numbers. These are used to identify characteristics of the spark plug. With these characters we can find out what type of spark plug, thread size, thread reach, heat range and other unique features of that part number. For example, the part number YR5GP can be broken down as follows:

Y – represents 14mm thread diameter, .460” thread reach, tapered seat, non-projected

R – represents resistor

5 – represents heat range

GP – represents fine wire platinum center electrode

A guide is available in our NGK printed catalogs that will help you break these part number down.
