For Sale: Lots of Autolite AR472 Racing Spark Plugs

[TurboDiverArt]

I used these plugs in my stage II heads, they will not fit in stock iron heads, they are too long. These are racing plugs, not street plugs. I have 182 spark plugs in total, 120 are loose, 62 in boxes, all are new, never installed in a head. Some are loose (not in a box) because I had index them to each cylinder so I knew what index ring to use without having to figure it out at the track, I should have saved the boxes! The gap has not been set on any of these plugs, they are brand new. I used to run these plugs in my TSO stage headed race car that I sold a few years ago. If you run stage heads you know you change plugs very frequently. I’d like to sell the entire lot. $250 for the entire lot (that's $1.37/plug!). If you buy the entire lot I will ship ground for free in lower 48 states.
