#4.Champion 810 Spark Plugs For Harley Engines

The Champion 810 Spark Plugs For Harley are a great replacement for genuine OEM spark plugs. This is a great brand and tends to run a bit expensive compared to others. We are of the belief that more expensive doesn’t neccessarily mean better. In this case, these spark plugs are good but they are not significanly better than the brands we mentioned above.

Overall, we think that the Champion 810 Spark Plugs are good quality and all and definitely perform as expected. They just don’t live up to all the hype that people credit them for. And it is precisely for this reason that we just put these lower on our list. Champion is a great brand in this industry and if you need reliability, it is a brand you can trust.
