You are buying one pair of Beck #3 spark plugs plus reproductions of the brass cooling fin "umbrellas".  This is the same Beck plug I sell for Knucklehead, UL, WL, WLA models which use an 18mm spark plug.  Neat part is the addition of the brass cool fins for your Knucklehead or flathead which has all the other really cool accessories.  The particular terminal nut at the top can be used with either rubber spark hoods or hooked terminals, however, with the umbrellas on, you will not be able to use these plugs with hooded wires.  I'm working on getting knurled thumb screws for these and will update the listing when I can get them.

These are fully-functional and perfect for your daily or weekend rider.  They look just like original Harley and Champion air-cooled 18mm plugs.  Unless you are going for a concours restoration, why pay $350 for an NOS set or take a risk on some 70 year old spark plugs which might not work?  These are perfect for the antique motorcycle enthusiast who likes to enjoy riding their motorcycle.!

Used from 1909 to 1947 on Single, Twin, Sport Twin, J, JD, F, FD, Pea-Shooter, JDH, VL, VLH, VLD, Knucklehead: E, EL, F, FL, ELC, ELA, Big Twin Flathead U, UL, UH, ULH, UA, 45 Solo: RL, DL, W, WL, WLD, WLDR, WR, WLA, WLC; Servicar G and GE.

They probably would also fit Henderson, Ace, or Indian Chief and Scout models as well as automotive applications.  Please do your research to make sure you can use 18mm plugs if you are buying for a non-Harley application or a 1948 and later Harley as they generally use 14mm plugs.
