The OS-F plug is the plug to use if you run four-strokes.
The Enya 3 is not working as good.
Why people sometimes say that pussles me???
I think most people over the world run their fourstrokes on
5-15% nitro fuel and doing so the OS -F plug is much superior to the Enya 3.
The Enya 3 glowplug has a OS counterpart and that is the OS 8 glowplug......and these these glowplugs work perfect in every Twostroke sport R/C engine.
Perhaps running on more nitro (20%)the Enya 3 glowplug is a serious contender to the OS -F plug but not on lower nitro contents!!!! (Havenīt tried so much nitro as most fourstrokes work perfectly with 10% nitro) Yes I know that some pattern flyers use as much as 30% nitroin their YS engines.
YS also has a fourstroke plug that is identical to the OS - F plug ...perhaps itīs made by the same company that makes
OS - F plugs???

Status: offline 		These discussions like this totally mystify me, I have nine Saitos, Two Enya's and a couple of other odd four strokes. I can pick out any one of them and take out the Fox Miracle plug and put an OS-F in and there is no change whatsoever, so I just don't get it.

How much nitro do you use???...As I said before the nitro content places a vital roll in how our fourstrokes behaves.
0-15% nitro and The OS - F plug is King!!!

Status: offline 		Just because my plane may be worth over $1000.00 doesn't mean I should no longer care how much I pay for a glow plug. If that trend of thought really holds true, then I shouldn't complain if each servo grommet costs $3.99, and each nut and bolt $2.99, should I? After all, my whole plane is worth $1200.

Fact is: O.S. is able to charge an exorbitant amount for their "F" because many RCers recognize it as having distintive value over other makes of plugs and are willing to pay for it. I personally have not seen enough of a difference to warrant that extra price, but I'm not about to dispute those who have.

It's supply and demand, pure and simple. If it comes a time where most RCers perceive no discernable difference between any of the 4stroke plugs, all the plugs will become "commodities" and any price premium will evaporate faster than ether spilled on hot concrete.

Now, it is possible that OS uses more platinum content per "F" plug than other less expensive plugs, and therefore it costs more. I don't know, but somehow I doubt it. The amount, in any case, is so small that it can in no way account for the sometimes doubling in price compared to other 4stroke plugs. Then the only other factor could be that OS makes far fewer "F" plugs compared to others, so the economies of scale disadvantage forces them to charge more. Judging by just how popular the "F" plug is among RCers, I doubt that also.

To me, the OS "F" cost more the same way a necktie cost more at Nieman-Marcus that at JC Penney. No one can argue with the "perceived value" viewed by those willing to pay for it. Ain't capitalism great?

Status: offline 		The YS plug is actually an OS F at close to half the price, is it not ? Check it out Another really great 4 stroke plug in my ecperience has been the Hangar 9 "Superplug". It gaave my YS-91FZ a beautiful personality after crankiness with the OSF and all others tried, though I believe this engine is something of an aberation from the norm, with a tendency to pre-ignition....Bogie

Status: offline 		Bogie, I agree, my last new Saito a 100, came with the new Super Plug, I have since bought four more and really like them. I have two OS-Fs for testing but have not seen any reason to use them full time. Nearly all my four strokes have Fox Miracle plugs in them.
JAKA, I use WildCat 10% Premuim Extra which has 18% oil with a couple of percentage points being castor. In my older Saito hi compression Saito 150 and .80 I had been using Fox 5% with 20% 50/50 lube. The 10% castor has not gummed up the valves as everyone predicted. Am going to try the WildCat it them too. By the way the Saito 150 when using the Fox Miracle plug and the 5% nitro idled with absolutely no shaking.

Status: offline 		I started using Fox Miracle plugs in all my engines about thirteen years ago, two and four stroke and I have only had a few burn out in all those years. I don't try to wring every last ounce of power out of my engines, if I want more power, I put a bigger engine in my plane. I recently started flying ducted fans with OS engines, and I use McCoy #9's in them, as that is the only plug any fan flier has told me would last in them. I cannot comment on other plugs, as I haven't used any others.

Status: offline 		I used the Fox Miracle plug for abour 12 years, good results, especially great idle from them, and thought they werte the answer to all plug problems, all the while wondering how to solve the violent detonation problems in my cowled engines in the 100 + degree heat here in the summer ! I finally detiirmined that the Miracle plug is a HOT plug - great except in hot weather, when it can really punish a good engine !.....Bogie

The import duty on manufactured goods containing that particular precious metal (platinum) is one reason I often hear .

Hobbsy -right on ! The good old Fox Miracle works and works !
The Enya #3 is another that works every bit as well as the OS "F" lasts forever and a week ,at least near this lattiude and longitude.

Status: offline 		I realize platinum is expensive but does anybody truely believe it is material cost that makes the os plugs more expensive? Truely material cost is only 1/10 to 1/30th the price we pay for plugs. The catalytic converter in any one of our cars has more platinum in it than a thousand glow plugs. Give me a break!

BTW I buy OS plugs because they are the best. I have good luck on the Saitos with the recommended McCoy 4c plug also.

Status: offline 		Take a look a the coil in a new OS "F" plug with a jewellers loupe (eyepeice magnifier) if you can get your hands on one.

Then, using the loupe, look at the coil in a brand X plug.

Chances are you will then see one of the reasons why the OS "F" plug is more expensive.

Quality. In material, design and construction. Look at how well formed and coiled the OS wire is. Top grade platinum wire too.

PS Steve, sorry to disappoint, but I think LF's spoken for!
