Rated 5.0 out of 5.0 by Don't waste money on other plugs The champion plug I have used work great on small engines time in and time out. For a lower price it works the same as the more expensive brands that cost much more. Plus noticed Champions are made in the USA, the more expensive ones on the shelf next to the Champions are made in China, which makes no sense. July 16, 2012
Rated 5.0 out of 5.0 by The Champion RJ19LM is my longtime choice for lawn mowers The Champion RJ19LM is a great spark plug for lawn and garden motor tools. The R means resistor plug. J is the physical specification including the thread, various lengths, etc. LM stands for Lawn Mower. The resistor plugs are mandatory in Canada to prevent TV interference. This has been my favorite lawn-mower spark plug for 25 years. May 20, 2013
Rated 5.0 out of 5.0 by Super easy to install, great replacement plug This was super easy to install. It's well-made and my mower which was hard to start up now starts up right away. Wish I had changed the spark plug sooner. It was such an easy fix. May 14, 2014
