Chonda engine spark plug replacement?

[slybunda]

my chonda unit came with this SAP branded F7TC model of plug. looking for a higher quality replacement, what equivalent NGK or Denso plug to get model number wise. is iridium available too?

 

[Spartanfool]

In my Chonda I run a NGK BP7ES.

 

[slybunda]

Is that gonna work for me?

NGK BP7ES

 

[slybunda]

Thanks i will get that NGK plug.
On further investigation the SAP brand is actually a Torch rebrand!!

 

[slybunda]

whats a resistor spark plug? iv seen some in the ngk range that are platinum or iridium but use a resistor where as the BP7ES does not have a resistor in it.

If your mower has an AM radio you would want a Resistor plug to cut down on interference...

 

[slybunda]

lol standard non resistor plug it is then.
does it affect wifi signals?

Hmm denso iw22 iridium seems to cross with that ngk part number. But the denso is resistor type. Would it still work?

NGK BPR7EIX is an iridium replacement, i have iridium in my chonda powered generator.

 

[slybunda]

Im guessing the iridium plug should last me for life with my usage of 10 hours a year?

I use the NGK BPR7EIX Iridium for that application. I have no idea why a resistor plug would not be needed or called for.

With NGK plugs - the 'R' in the model number - it is a resistor plug. Either or will work, I just usually get the R version because it doesn't make a hill of beans difference to the spark....in the real world it either works or the ignition is shot.

 

[slybunda]

does resistor reduce spark power?

What size engine is this?

 

[slybunda]

212cc in pressure washer

 

[dlundblad]

I have a HF engine that size I believe they put a name brand plug into. I can check that if you’d like.

Perhaps you can just get a plug for a Honda that’s that size.

 

[slybunda]

will get a hold of the ngk plug its cheap enough.

The resistor accomplishes two things. 1. It limits the current of the spark but, not the voltage so plug electrodes last longer and 2. ir suppresses RF radio and TV interference. Ed
