NGK VS Bosch and Plug Gap questions.

[JOE.G]

Hi, I Run NGK in my saws, and my Stihl 4 Mix stuff came with Bosch, I am thinking of going to all NGK. How does my chart look? The FS110 R is the only one I am getting mixed information as far as heat range. .020 Gap for all of my Items? Thanks

Stihl FS 110R Bosch USR 7 AC NGK CMR5H Hotter Match to Bosch/CMR6H Cooler Electrode gap: 0.5 mm (0.02 in --0.020 In

Stihl BR600 NKG CMR 6H or BOSCH USR 4AC Electrode gap: 0,02 in. (0,5 mm - 0.020 In

Stihl HT131 NGK CMR 6H Electrode gap: 0.5 mm (0.020 in)

Stihl 009 Bosch WSR 6 F or NGK BPMR 7A Electrode gap 0.5 mm (0.02 in

Husky 562 NGK CMR6H Electrode gap: 0.5 mm 0.020 In

Husky 450 NGK BPMR 7A/ Champion RCJ 7Y Electrode gap: 0,02/0,5 - .020 In

Husky 55 Rancher Champion RCJ 7Y/

NGK BPMR 7A

Electrode gap: 0,5 .020 In

.020 is correct, always worked good for me. I received chainsaws with bigger gaps that would not run right until gapped. 020. I don't think plug brand makes enough difference to change unless fine tuning your heat range.

Bosch production went to China so I stopped buying them.

Whatever you choose to run, make sure you're buying it from a legit store. Buy from Amazon/Ebay, and you might get legit, or you might get plugs made in the same factory as Torch.

I usually grab the plugs from my local dealer, I placed a Order for some parts from Jacks small engine online so I just added them to my order, I would think they sell legit plugs I hope.
