Doesn't match identical with Softail slim 2018 hd plug
Product looks good but not comfortable with the difference in spacing between Harley plugs and these. These are slightly longer than Harley plugs from threads to top of plug.

Check your gap specs for your bike
They say pre-gapped, but mine came in not anywhere close to what my Sportster called for. One was at .028 and the other at .030 - my bike calls for .040. I was able to successfully gap them and install - bike started right up without hesitation and rode great. Friends recommended these so only time will tell how much better they are than stock plugs.

Great plugs
Perform well in my 2011 Harley FLHTK 103. No issues with fitment, look good, good value, bike start after install.

Check your gap
Not gapped at 40 it was more like 28, but still the best plug on the market for a Harley
