Raisman plugs?

#1

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.

Wow.
They "sound" more impressive than I would have thought.
I am somewhat encouraged.

Raisman sells a lot of aftermarket chainsaw parts that are NLA from the manufacturer. Are they the same as OEM? No, but it is better than throwing a good Stihl chainsaw away for a plastic part. I have used a few af their carbs without issue. HL Supply carries a lot of Raisman saw parts.

Basically I use mostly NGK plugs now as to reduce my inventory but here is a spec sheet for the NGK that might help to confuse things even more.

From the chart you see that the BPR5ES (4006) and the BKR5ES (2460) are the same plug just different hex size so I am dropping the 4006 plugs in flavor of the 2460 plugs. What is better they cost they same. Actually the 2460 went down and the 4006 went up. One distributor says to sale them at $5.24 but my current supplier as the retail at $3.14

And I too having to use a lot AM parts as OEM are trying to force the customers into new equipment. Just a business model that I don't like as a repairman.

It just like Stihl demanding Zama (Stihl owes a controlling share of Zama) to no longer sell carburetor repair kits or carburetor that fits only Stihl products via the distributors so Stihl can sale only new carburetors even though they claim they have carburetor repair kits which my dealer can't get. Just a profit making scheme.

What worst one the Zama offices is just North of me in Franklin, TN.

Often the rc12yc where recommended is a bit cold and in fact B&S has said if the plug is blackened to move to rc14YC which we find more often than not is the plug to use.

That engine takes a BPR4ES plug. NGK plugs are like this the lower the # the hotter the plug. Where as the champion runs just different the higher the # the hotter the plug. We are having a lot of trouble getting the NGKs so are using the Champion RN12YC instead. Looks like the only difference in the RC12YC and the RN12YC us the size socket it takes to take it out since the heat range is the same.

Kawasaki Mules model 600 and 610 had trouble fouling spark plugs, many machines affected. Had a few people go to the dealer, they'd put new a carb on or clean the old one, etc, still after a few hours, plug would foul.
I finally found that switching from a BPR6ES to a BPR4ES cures the fouling problem.

Usually the original plug listed is for the engine to be be used under heavy load and at fairly high ambient temps. If equipment is run under light load most of the time very common to need a step hotter plug. I have a few customers i put in the RC14YC plugs. My favorite spark plug story is the guy who had champion plugs in a macine that were way too cold of a plug and they fouled all the time. Auto parts store sold him some autolite plugs like 3 steps hotter and the plugs don't foul any more. To this day he tells everyone champion plugs are s#!t and autolites are the best.

Plugs are a crap shoot . If it runs well with xyz buy more xyz .
Thousands of new Waukesha 7, 000 cu. in.industrial engines had always used champion but this new engine came with NGK . SHRUG

At around 2:00 am it was down day 1 . Solution ; replace plugs with champion .

Had a 1965 Chevy wagon and was going to tune it up. Told the guy from the parts house I wanted Autolite plugs he talked me into putting Champions in it. It ran 3,000 mile and fouled the plugs. Got Autolite and put in it never fouled another plug. Like I have always said for my use I would not screw a Champion plug in a bucket of dirt.
