Substitue for Kohler spark plug

#1

nbpt100

The Kohler spark plug the XT6 series engines take is a Kohler #14 132 11-S1. When I go to my various local auto parts stores they do not carry Kohler branded plugs.....they come up with a slew of substitutions. I don't mind a substitute if it is basically the same specs, heat range included. I know stores will x-ref to plugs with the same threads and basic physical size but other features may be different.

My on line research shows a few people are using as a substitute the following two plugs:
Champion RA8HC
NGK DCPR6E

From the part number you can see the heat ranges are different. One is an 8 while the other is a 6.

Can anyone confirm if one of these substitute spark plugs are direct replacements or do you know of another that is a direct replacement for this Kohler speced plug? Thanks.

Not sure about the champion, but the NGK number is a direct replacement.

I just got this from a reliable source. The RA8HC is also a direct replacement. With Champion the higher the number the hotter the plug while with NGK it is the lower number is the hotter heat range.

If brands are using different scales, is there some way to compare heat ranges between brands? If I have two plugs in my hand I can compare all of the dimensions and get a good idea of which runs hotter or colder. But when you dont have that at your disposal is there some reference chart that will specifically address heat range? I know there are x-ref charts on line but from what I can tell they play it loose with heat range. Just because a plug physically fits, it does not mean it is an ok choice.

Apples and oranges....
Both plugs are the same heat range (just different representative numbers) and are absolutely interchangeable.
An AC plug will have a different number again.

I use this site to cross refference plugs https://www.sparkplug-crossreference.com/
Note that heat ranges overlap.
Champions tend to be coarser than NGK's

Other than that there are a lot of charts on the web comparing the heat ranges of different plugs.
The Stens & Prime Line web pages both have charts of spark plug applications.

All of the spark plug companies have decoding tables so you can work out what all the letters & numbers mean.

Thanks! I try to stay with the brand that makes the plug for the Engine manufacturer. It has become obvious to me that Champion makes the plugs for Briggs. Not sure about Kohler. I would lean towards NGK. But I do not know. Anyone out there know for sure?

I always use NGK anymore for everything.
I have a 23hp twin cylinder Kohler and I used NGK Iridium last time I changed the plugs, and they've worked great for several years now.

Wow! Too many choices for this old fart.

What's that mean "coarser?" How is it relevant to the selection decision?

Flip a coin.
Champion likely makes the Kohler plug.

Use whichever one you like. Frankly, heat range makes little to no difference on these engines.
You will notice that Honda takes the same 140 and 160 engine and some come with a BPR6Es and others come with a bpr5es which is one heat range hotter.
I think I looked up one time and found that one was technically expect for the pressure washers and one was for the lawn mowers but nothing about ANY of that makes sense.

It is very similar to the fact they spec a 10W30 oil for all of their outdoor power equipment that's not a snow blower or something super cold just so they can have uniform I guess or just because it's simpler and easier.
There is absolutely nothing about their engines that would require a multi-weight oil and in fact most of your HD 30 oils would offer better protection if you were to actually test these engines under hot and extreme conditions and then take them apart and look for scuffing marks on the cylinder and especially the piston skirts.
But in reality this would be a waste too because as long as these engines have oil in them none of these tiny wear or scratches etc usually even form and they never cause a problem anyway.
It's just like people wanting to put synthetic oil in their lawn mower because it makes them feel better!
Their mower doesn't need it.
These things can run 40 years on a standard 30 weight oil so it's absurd to spend more money for a synthetic but as I said, it makes them feel better.

I've been using 30 weight oil in Hondas for decades and I use whatever plug crosses to whatever else.

I can't stand the color plug because it uses the 18 mm hex head which is completely STUPID!!!
I will take them out and throw them away just because I don't like the size socket that fits them.
Luckily, all the other ones that cross to it will use a 5/8 which is what they're supposed to have for an overhead valve engine like this.
This is the way it is and this is the way it shall be.
I also can't stand the more recent string trimmers and blowers with that tiny threaded plug.
Again, it's completely stupid and doesn't help anything.

Yes but I wouldn't have a Kohler plug in my engine even if it is an XT series engine because they use the wrong size hex head! Lol
That was an absolute arrogant, jerk move on their end.

RA8HC definitely works. I use them to replace 14 132 11-S1 about 20 times per year for my customers. Never had a problem. I always have them in my inventory.

I use the Champion Copper RA8HC, I never have any issues with good 'ol Champion copper plugs. The part number is Champion 810 for parts stores. Why in God's green earth Kohler had to produce an engine with an oddball plug is beyond me. Virtually all OHV engines use the Champion 71 (RC12YC) plug.

Because we don't put an overpriced plug into an engine that is not giving us any higher quality for that price.
In fact it gives us extra aggravation due to the non standard size.
I refuse to use them - just because I can.

I've always trusted Champion, but I have to search the number myself because parts people think they are all the same, so they just sell you the first one they grab that is packaged as a "lawnmower spark plug".

Don't get me started on Champion plugs. Lets just say the best place for a Champion plug is the bottom of the dumpster. Those things have cost me more fustration and expense over the years than any other branded plug including the dreaded Torch.

Hello ILENGINE,

I agree with you when it comes to most automotive applications, but I just have not had issues with Champion on the small engine stuff.

It's for sure most resistor plugs are worthless if they have been dropped on a concrete floor or mishandled, because the barrel resistor inside the porcelain gets cracked. Drop a couple of known good old ones or new ones and then test the resistance (before and after) with an Ohm meter.

Kohler does not actually manufacturer their spark plugs, but it is hard to track down who does. I suspect NTK/NGK makes them under a private label agreement contract.

Many filters, oils, plugs and other parts are made this way for most assembly plants and manufacturers.

I used Champion exclusively up until I had a shop pack of J19LM plugs stop sparking after running in several different engines for as little as 3 minutes. Put 5 plugs in the same mower one day, and then had to replace it two days after the customer pickup up the mower because it died while mowing.

Just had issues last summer with Champion plugs in a Kawasaki engine. Had to attempt to use Champion because NGK were not available and all 4 plugs I tried in that engine would not restart hot. They would work after cooling off, the original NGK that I took out didn't give those issues, as well as a different NGK heat range plug that I also tried.

I don't use the J19LM plugs very often because the heat range is so high.

Going old school, I normally run and engine 15 minutes or so (high RPM under load), pull out the plug(s) and expect to see a very faint light tan appearance on the electrode porcelain.

I have found high heat ranges are usually better for cold weather and rich fuel conditions.

Down here in TX, usually a "12" or "14" heat range holds up much better.

Most manufacturers have gone up on heat ranges in past years to appease the EPA types that want to do away with all gas small engines. The theory is a "hotter plug" is supposed to be more combustion efficient. Unfortunately, hotter combustion temperatures also result in eventual combustion chamber and valve damage.

I have been reading on various boards that some people have recently had problems with Champions. I never had. But I do not change 100 plugs a year. I wonder if they are getting counterfeit plugs. I buy all of my plugs from a local auto parts store not on the internet.

There was an article i read on the internet (must be true) that most of the plugs on amazon are counterfeit. I get my plugs from stens and another reputable online source. Took a plug out of a honda once that i was pretty sure was a counterfeit NGK.
