Experiences using NGK 3066 vs cmr7h
I personally have the CMR7H plugs, but from what I understand, the 3066 is an equivalent plug.
CMR7H: http://www.rcnutshobbies.com/SPARK_P...ark_Plug-.html
3066: http://www.fgsupply.com/search.cgi?keywords=cmr7h
What are the differences between these two plugs or are they exactly the same? If they are different, how does one perform better than the other?
Unfortunately, there is very little information on these plugs in RCU, there are only two existing threads, and they are both very old and none of these guys even describe their long term use of either one.

http://www.rcuniverse.com/forum/m_21...tm.htm#2165562
As for NGK plugs, I found this link where they are being sold very cheaply, $3 each is a steal.

Also, does anyone know if there is such a thing as a performance version of these plugs? (I.e platinum cores, etc.)

I think the 3066 is the OEM part number and the CMR7H tells the heat range, plug thread length and so on. $3 a plug is cheap but after shipping what is the price. I get my NGK plugs at Advance Auto for $4.

RE: Experiences using NGK 3066 vs cmr7h
Thanks for the tip!
Ill order a couple of those iridium ones, but I will see if there is an Advanced Auto around my town, $4 is sure a bargain for getting those plugs locally. (I am surprised that morons on the net are trying to sell these plugs for almost $12 USD!

Tower Hobbies gets around $12 for the CMR7H and I am like you cannot see paying over $4 which to me is high but it is a specialty plug. I am sure there is not a lot of call for them like most plugs that are made for 1 to 1 cars.

RE: Experiences using NGK 3066 vs cmr7h
Another thing I have heard is that Champion also has an equivalent plug for our RC engines. The same with Torch (I think)?
What are the model numbers of thes other brand plugs that are equivalent to the cmr7h/3066?

RE: Experiences using NGK 3066 vs cmr7h
Going by what I have read on the forums dealing with the HPI Baja the Champions do not hold up as well as the NGK and if I am not mistake cost more. I know I do not get near the mileage with Champion plugs on my motorcycles as I do other brands. All so MANY years ago I had problems with Champion and it left a bad taste in my mouth.

Irridium plugs once soot fouled cannot be cleaned, if you're a tad rich they'll foul...I tried them in my dirt bike days, the platinum plugs are the same, I went back to using standard plugs. I don't believe there's any performance gain to speak of that's worth the extra coin.
Here in Canada Lordco sell the cmr7h for $5cdn, cheap enough to have a few new ones in the toolbox. Can't see how online sellers justify $12 a plug and probably $7 to ship them but I guess there's takers...that or they have a full box of plugs sitting on the shelf.
The cmr7h came fitted in all my small engines ie: weed wacker, leaf blowers etc so it is a commonly used plug just not used in the numbers like car plugs are.

They also sell the Rz7c plugs @ MENARDS under the McCulloch name brand in the chainsaw section for only 3.25 each.. I've been running these in my Firehammers, and baja for awhile now...

I guess this thread is a little old but I wanted to share that I picked up a couple of NGK CMR7H (3066) plugs at Auto Zone for $3 each. That's the best deal I've heard of for them.

RE: Experiences using NGK 3066 vs cmr7h
lol old indeed. Anyway to answer the OP, 3066 is NGK's part number for the 7H plug, they are the exact same thing - its not an OEM thing, its just the part number on the retail box for the 7H.
Your also wasting your time with Iridium plugs in these engines, there is no performance benefit at all vs a clean NGK plug in good condition. Also they are taller so more likely to get broken.
edit: and from what i've seen most people are running in the wrong heatrange anyway and would be better off with a 6H.

I get mine at O'Reilly Auto parts for $2.59 each.

RE: Experiences using NGK 3066 vs cmr7h
I too will have to check out OReilly's. I know they have a major distribution point where I'm at, but I have not personally seen any stores while driving about. I will have to bust out the ole' phone book and look up their store locations.
As getting a whole box, I did pick up a box of 10, I think they worked out to be like $3.50 USD each.

RE: Experiences using NGK 3066 vs cmr7h
I know this a bump but I had my spark plug get fouled up from extremely rich carb setting. I ordered 10 plugs from Auto Zone for 3.50 each and they are grabbing them from the warehouse for overnight shipping. It's great
Auto zone rules... I buy everything from there for my mazda
I even bought a Camry heatercore radiator for my water cooling setup years ago (for my pc)

RE: Experiences using NGK 3066 vs cmr7h
For the price of these NGK CMR7H plugs, yeah, they are a damn good price. I have not tried to buy them from O'Reilly's yet since I have not yet gon through all 10 plugs from the box I bought last year, but fro $2.50 each, I will hit them up for my next box of 10.
I believe both Autozone and O'Reilly's are are direct distributors of these plugs thus their ability to sell them so cheaply. (Buy any NGK plug through an RC seller, and you will be paying anywhere form 3times to 4times as much. Cutting out the middle man really saves alot.)
