AFR 14k refers to an air-fuel ratio (AFR) of 14 parts air to 1 part fuel by weight, which is considered the ideal stoichiometric ratio for gasoline combustion in internal combustion engines. This ratio ensures complete combustion, maximizing efficiency and minimizing emissions. Deviations from this ratio can lead to rich (too much fuel) or lean (too much air) conditions, impacting performance and engine health.
Well, darling, "afr" stamped on your 14k gold bracelet stands for "Africa." It indicates that the gold used to make your fabulous accessory was sourced from Africa. So, now you can flaunt your bling with a little extra geographical flair.
