6v glow plug options

I was looking up the 6v glow plugs (part # md092392) and I found them for anywhere between $30-60ea. But I also found the same part number as a Hyundai/Kia glow plug for about $7ea. They also list the same alternate glow plugs for both manufacturers. Does anyone know if these are actually the same parts?

I really can't see spending seven bucks and expecting any quality. In fact, I'd be concerned that they could harm the electric system. I would spend the money and get the Mitsu OEM 6.2V green tops as they are meant for this system. It's not like getting after market brake pads or something like that, GPs are an integral part of the system. If the impedance is wrong, the system isn't going to react correctly.

Does anyone happen to know what a good known impedance value is of a green top glow plug? I have an aftermarket set coming and I triple checked the cross reference before I bought them. I'll certainly measure them against the originals I have installed but it would be nice to know the hard values..

My old Green tops have a resistance of 0.4 ohms. It may be a little less but I only have 1 decimal point on my multimeter.

I wouldn't assume an aftermarket glow plug will work with the ECU simply because it has the same resistance when cold, though I guess it's a good starting point. The change in resistance as it heats up is also important.

I'm definitely curious to know what you find out.

IDK why not necessarily. The glow plugs are listed as OEM Hyundai parts with the same part number and the L300 was sold/rebranded as a Hyundai model...

But, the parts are/were unavailable at the time so I bought Mitsubishi ones. They measure at .4 ohm ea as do the ones I'm replacing.
