NGK Spark Plugs - how to decode the letter & numbering system

Ever wondered what the number & letter code means on the side of an NGK spark plug? Well, finally, they caught my attention after all these years so I did a little research to find out more...

In this video I run through how to decipher the Spark Plug code - for example, a BPR8ES? What does it mean? Well, you may be surprised to know that each of the characters has a specific meaning & here's how to decode it...

I have really only brushed the surface on the NGK coding but I'm hoping this video helps give you the basics so you'll know how to decode your own spark plugs.

Here's the link to NGK's 2015 Motorcycle Spark Plug catalogue - lots of really useful info & it includes the decoding table I used in the video:
