what's the difference between DR8ES-L and DR8HS

[Tri-ZNate]

I have like 9 plugs here that go to a 110 brand new and they are all DR8HS and my quadsport plug fouled and thats a DR8ES-L. Now after looking at the 110 manual it says the 125m came with a DR8ES-L so I'm thinking the DR8HS is just a cooler plug?

check the thred length on them I think HS is 1/2 long and the ESL is 3/4 long

The "8" denotes the heat range in both plugs. The "-L" is one half a heat range higher and the "H " means part threaded. With a KLG plug the lower the number the hotter the plug. Dr8es-L is the Canadian plug with the "R" standing for resistor. You can switch to the American plug D8EA if you like.

Yeah, HS is a lot shorter (2 to 4 threads, i think) than the ES

well it performed beautiful today so there wasnt a big difference between the plugs
