Can anyone here post how to change the ignition coil wire suppressor cap to the SP. We have quite a few alternatives to the Bosch YR7MES plug in NGK, Champion, etc. Is there any way we can just change the wire with suppressor cap cable to spark plug or just the suppressor cap alone. I saw some online where they have a push screw type suppressor cap that can latch on to the terminal nut of SP.

Hello, as I can see the wire is not separable from the coil, but perhaps the cap is separable from the cable. Often the cap is screwed to the cable.

Unless there is a problem with the Bosch plug, I would leave it alone. Disconnecting the cap from the HT lead to replace with a new cap may lead to other problems and if a warranty issue came up, you may be denied because of the tampering.

Bottom line, if it ain't broke, don't fix it.

I have searched using Torch and got no where.

What I know about 'Torch' brand spark plugs is that the very first commonly-recommended way of coaxing a generator from the Far East to run better is to yank out its Torch, Bongodongo or whatever other OEM plug they came with, replace that with its Champion, AC Delco, NGK or other brand name equivalent, and perhaps then use the Torch as a fishing weight.

Anecdotally at least, with my pair of little 2-stroke 900 Watt Harbor Freight primitivo fussbucket gensets that came with Torches, I can confirm this notion. After their swap to Champions both gensets immediately began starting MUCH easier and just seem to run happier and steadier and even a bit quieter, without all the previous "seeking". This has actually been noticeable and even measurable in their far more even power output too as measured both with a digital multi-meter used to fine tune their idles under load and hence voltages, and also on board my boat with its analog AC meter for shore power. Its needle no longer sways like a metronome.

So yeah, if I had a Meteor I'd be very happy to find an equivalent replacement for a Torch plug.

Folks, had been to the dealer for specific concerns on my fuel gauge incorrectly showing up levels. They indeed found the problem and waiting to get the gauge replacement part. During that time I asked them if we could use a different spark plug and plug cap. They showed me the plug cap is easily removal as its a screw type threaded to the ignition coil. They suggested me to get a replacement threadable plug cap that can take in loose or solid terminal nut plug cap from NGK or any NAPA store.

Now this opens up plethora of spark plugs now that can be used that are much better the stock provided. I was suggested NGK (4288) PLKR7A Laser Platinum Spark Plug that has the same dimensions of the current torch/chinese bosch made plug YR7MES. This is available on amazon.com for $12 with tax and is the perfect fit but solid terminal nut. I have read great reviews on this SP and waiting to get it. Keeping you guys new information received.

Use caution when buying these, or any plugs on Amazon, eBay, etc. Lots of fake plugs for sale under the NGK brand name.

Of course, the dimensions of the plug are important, but more important is the heat range of the plug. It seems most buyers of this plug own Mercedes cars, and those engines operate at lower temperatures than our air cooled engines. This plug may be hotter than the OEM Bosch plug.

Got these for my Meteor…lots of good alternatives for using solid terminal plugs with these NGK caps.

Were these direct fit? What's the part no of the spark plug, please?

Thanks

         Isn't it shown in his picture of the plug?:  LKR7AI

[GSS]

Apologies for the delayed reply. These were a direct fit.

Here are the part numbers.

[usasmartindian]

GSS, thanks for the part numbers. Few clarifications and helpful. The plug comes with .8mm gap. for Meteor 350 the specification is 0.7mm - 0.8mm. Did you adjust the gap or just used the OEM setting on the plug. Also, did you notice any difference on the performance post change in comparison to the OEM plug (torch one called Bosch). Appreciate your experience after installation. thanks!

[GSS]

The stock gap was within specs, so I did not make any adjustments. In general, I stopped regapping new plugs well over a decade ago, as this truly makes no perceptible difference with current electronics. Engine starts and runs flawlessly, so no change from baseline. Won’t have a proper assessment until after it warms up below freezing in April.

GSS/Others,

Got the NGK spark plug today and installed on my bike. Did not change the gap and installed using some anti seize. Turned on the bike and started with just a click. Rode the bike and it was smooth and quite peppy. Yet to drive for few miles as weather today was cold. Will edit and comment post my ride. Looked peppy and smooth post plug change.

Hi GSS,

So what was your opinion of the NGK plug and new cap you installed?

This might help ?    I'd like to go to the iridium myself !
