    The last time these were changed out in the engine I’m putting them in was likely in the 70s so I’m hopeful these new ones go just as long.
    Fits the farmall m and the smaller starter motor on the john deere R, likely will fit or is the right plug for all sorts of farm tractors from the 30s through to the 70s.

    Received a Champion D16 spark plug August 17 that was crushed during shipping and subsequently damaged. The ceramic is cracked and the seal is missing making it useless. Neither Amazon or Champion have responded to messages

    Best plug for my engine. The price varies with the vendor so be careful. This is a single plug. I purchased several January 2020 at $2.79 which is a good price. It is the plug I have been using in my GaryMarine 4112 engine for 30 years. They are getting more difficult to find so I just ordered 8 more from my local auto parts store.

    This spark plug was a perfect fit for my 1960 vintage single cylinder British Seagull outboard motor. Time will tell if it’s the correct heat range for the engine.

    I’ve been using Champion 18 millimeter plugs like these in my 75 year-old Harley for the over-40 years I’ve owned it. The plugs I bought are catalog 516, also “D-16.” I go back with this plug since they were cataloged as “UD-16,” in the 1970s.
    My old Harley uses oversized 18 mm sparkplugs that are commonly known as “tractor plugs,” that have been used in farm machinery for decades before that. I liked finding them in boxes of 6, and pretty inexpensively. The price was right!

    This D16 Champion is a perfect match for the OEM spark plug for an antique Onan W2C generator.
