China spark plug to NGK

What is the difference between a normal plug and a "resistor" plug? will it change the performance or anything like that?

My local pitbike shop said that the cr7hsa is to be used on electric start engines and the c7hsa should be used on non electric start engines. I dont know the difference. Iv been using cr7hsa because i did have electric start but i will change the plug to a c7hsa. Maybe there is a difference. I did notice the fair bit of difference between a china plug and a ngk.(GET RID OF THAT CHINA PLUG!!!)

my lifan 150 (pitpro 150xr) seemed to come with a ngk plug. im wondering a little if its a fake knock off or a genuine ngk. any real way of telling?

they use resisted in cars but theres no need to use them in bikes

i used to buy NGK "R" plugs for my cr, they cost around 20 bucks each and aparently they are for racing on the NGK logo it says NGK and R in a different font underneath them, they were a lot better than standard plugs but when you fouled them up it was pretty annoying throwing $20 away each time. i dont know if thats what you guys are talking about but thats what ive come across

You probably bought irridiums. They are IMO not worth the money on street cars, and make no more power than copper plugs.
$3 coppers vs $20 irridiums...
