Raisman plugs?

[Chartman]

I’m usually just a lurker in this neighborhood, but I do have a question now.
I bought a tuneup kit for the Kawasaki FR651V engine on my Cub Cadet Model: 13WFA1CT010; Ser#: 1H145H60350.
The spark plugs that came with the kit are Raisman RC12YC.
They fit in the engine well enough, but they appear considerably less “substantial” than the ones I took out and they take a smaller socket (16 mm?) than the old ones (13/16"?).
The ones I took out are Savior BPR6E, which I never heard of either, but they ran fine all last year.
I’m wondering if there is a prevailing opinion about the Raisman plugs; something along the lines of:
- “Yeah, these are okay. I’ve used them and (almost) never had a problem.”
or
- “This is “aftermarket crap”. I wouldn’t use them, but you’ll “probably” be okay.”
or
- “Get those things out of your engine before they blow the thing up!”

Thanks, in advance, for your thoughtful response.

The company is from Brazil but the plugs are made in China. https://www.raisman.com/collections/spark-plug-4/products/spark-plug-for-briggs-and-stratton The ratings online from people who have bought them on ebay and amazon are generally 4 or 5. If concerned why not look for Champion, NGK or Denso plugs that fit? Those are usually reliable.

I will tell you that Denso has a cross reference of most plug manufacturers and neither of those companies show up.

I use quite a few Raisman parts on chainsaws but i don't use the spark plugs. I have not personally seen a Raisman plug fail but then again I don't put them in customers equipment in my shop. I use champion and NGK plugs. I have had plugs that come in the super cheap Amazon and Ebay kits fail quite often. I will assume the Raisman plugs are just rebranded from a manufacturer.

I never put a chinese off name plug in an engine.
NGK, Autolite, Champion or Bosch for me.

Hi,
Thanks all for your thoughts/input!
I think I will leave the plugs in and give them a try.
(...since no one so far has gone with my third sample response.)

If I pay close attention to engine performance and inspect the plugs after a couple of uses,
I don't think I will go too far wrong.

RC12YC have always been 5/8 (16mm) hex. But not NGK make the same plug with 13/16 or 5/8 hex depending on the part number. Some equipment is too tight fro the 13/16 hex so I install the 5/8 hex version without ill effects.

main thing to watch out for is the length of the threaded portion and how far the nose projects compared to the old plug(s). Some plugs are coated to make seizing less probable in aluminum.

Good point, sgkent!
The body of the plug I replaced was slightly longer than the new one, but the threaded part that projects into the cylinder was the same length.

don't want it to hit the piston

Never heard of them prior to this thread, & I'll stick to my NGK plugs..​
