    1 spark plug
Original Equipment Spark Plug is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Stick to the original Why would you want to deviate from the OE plugs? They are similar in price to other plugs and they run great. I just replaced mine and it runs like normal.

Rated 5 out of 5 by from Can't go wrong using on a basically stock engine I have always used this spark plug...once I went with a "upgraded" spark plug that cost way more to find that it ran the same #couldn't tell the difference riding let's say# but the engine light would come on #guess there is a pick up inside the plug on original plug that other spark plugs may not have...needed on the 2007 Wide Glide# and the light would stay on for a little while then go out and then back on; so on and so on...quickly I went back to original type plug and engine light went off for good. For $3.95 and a plug that does the job perfectly and you can change out cheaply any time you want to, why not go with what the bike comes with #and in my case a plug my bike approves of#? I usually change out every spring and every fall #so every 7-8 thousand miles...more often than needed I suppose# but for less than a couple of min and for less than a $10 bill what is there to lose is the way I figure it, for a bike that runs perfect with no engine light coming on.

Same Part?

Gonna change my own spark plugs. Long story short: I bought plug w/same part number(32342-04), however the plug number(5R6A)differs from manual(6R12). Are they the same?
