You are buying one pair of Champion D-16 spark plugs with the new air-cooled adapter kit made in Europe. The difference between this kit and the one we've sold for years is the base is cad plated not zinc on these this is also significantly cheaper than the other ones. Comes with the bases, base retainers, D-16 plugs, and knurled thumb nuts. The bases are reusable.
We do sell this kit separate without plugs, though the plugs are a fairly insignificant part of the cost.
These are genuine D-16 18 mm plugs which works out to a #3 heat range for Harley-Davidson motorcycles. This kit is pretty neat, it utilizes newly-machined air cooled hex with original styled threaded retainer rings which the original air-cooled plugs were equipped with to help with cleaning. These are adaptable with other heat ranges using the same 18mm hex design from Champion. Not sure about other brands if they will fit or not.
A note on shipping:

We have a no-hassle return policy, and we stand behind the parts we sell because we know what we are selling and shipping to our customers. Before you make a purchasing decision compare our feedback vs. others.
We are aware eBay’s shipping calculator is not working correctly on combining shipping for some of our listings. If the shipping amount eBay is trying to charge you seems high, please contact us immediately or simply click “request total from seller” and we will promptly manually calculate your shipping. We always combine shipping on multiple item orders and will find the least expensive method which falls in line with how quickly you need your items. Thank you!
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.
We also offer several different plug accessories like cool fins, umbrellas, plug wires, plug wrenches, tune up kits, etc.
The pair you are buying here is fully assembled and will arrive with the spanner wrench as shown in the first two pictures. You can remove the air-cooled structure and place it on subsequent sets of plugs over the years as you use up the plugs. Quite a neat idea!
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.
Please understand sellers on eBay do not set the shipping rates. Please also understand that sellers are charged a final value fee on the amount of shipping you are charged over and above the fees they pay on the sale and the Paypal transaction. In addition to that, sellers have the expense of labels, shipping materials, padded mailers, etc. I do charge a handling fee on some items, but I also offer several shipping options whenever possible to give you more affordable shipping choices. If you ever think the shipping fee charged is too high, please let me know before leaving a low rating on shipping charges. It’s rare that I receive such feedback, but I work hard to keep my customers happy. I’d rather know if someone is unhappy before they leave a low rating. That’s the only way I can solve a problem. I don’t ever want a customer to go away unhappy!
