It’s a little pricey for just 1 spark plug but works great

Check gaps mine were a little too big and had to be adjusted.

5.0 out of 5 stars Way better than stock CPR6 Grom plug
Reviewed in the United States on July 6, 2023
I have a Honda Grom, which ships from the factory with a CPR6 plug. Honda recommends the CPR7 plug for the American market if you plan on running the bike long and hot. I changed the spark plug at the 1,000 mile mark- let me tell you what, 3,100 miles later this thing feels so smooth, even after running the bike nonstop on 55 mph mountain roads (Blue Ridge Mountains) for two hours straight several days in a row. I have absolutely no complaints.

5.0 out of 5 stars Good spark plugs
Reviewed in the United States on April 21, 2021
I've had multiple pairs of these spark plugs in my yamaha cruiser over the years and I've never had any problem whatsoever. Even after putting a ton of work into the engine and tuning, no problem at all. Great spark plugs for a great price.

5.0 out of 5 stars Good, I guess
Reviewed in the United States on February 22, 2021
I've been running my 2011 V Star 950 on them for about a month now. No issues. I guess that's a good review; they either work or don't right?
