Review on NGK DCPR7E Spark Plug Pack by Dan Dickey

Great fork at a great price! I've been working and building engines since my age taught me how to put dots on my 47 fist at the age of 8. I use NGK in all my scooter engines especially the V-Twin engines, both OEM and heavy duty and they burn great. They also process rich mixtures very well. But they get dirty after a few hundred kilometers on a rich compound. When they start to get dirty I just give them a really good clean with a mini wire brush, clean the brakes and use them a second time and/or use them for emergency backups.
