What are these sparkplugs for

[merc_man]

Got a few of these plugs at an auction. Anyone know if they are good to run in saws?

Bosch wsr6f is for all stihl saws and non 4 mix products. That NGK is typically echo but stihl uses them in some things as well

Same heat range as the NGK so probably interchanges. I had one of them in a 257 Husky and she ran great.

I have that NGK plug in an Echo limbing saw, you should be fine. Would not trust Bosch these days. Use Bosch as a sinker when you go deep sea fishing. Hope you catch a big one.

Stihl uses NGK as their OEM due to qaulity control issues with Bosch
