Coil compatibility

Quick question, I have an 89 1100, will coils from a 2002 1100 work? I'm hesitant on the cheap new coils on ebay, the new oem ones are really expensive, and I'm hesitant one buying used ones that are 30 years old. Looking at the pictures they physically look the same, just didnt know of there was anything else I should be concerned about.

I looked at some on ebay just for curiosity, and they look the same, if you can measure the resistance of the primary that should narrow it down. It looks like the number on the case is the same, so maybe perfect match.

Looking at part numbers on the fiche the are the same up to 99, then the part number is different 2000 to 07. I'm wondering too if anyone has tried it. The one I'm looking at is on ebay so I cant really measure the resistance. They do look identical.

If it helps with hunting the correct coils down the ones from the '98 to '03 750 ACE are also 30510-MM8-003.

If I was betting with your money, I'd bet that the 30510-MCC-003 is an interchangeable part and just a running production change over time.

I found a cross reference for everything that part number fits and I'm going to take a chance on a set off a 2010 vtx1300. If this works I'll post up the reference I found as this really opened up the possibilities.

Funny, I just checked mine today, Primary - 2.3 ohms, Secondary - 23 Kohms, Spark plug wires - 5.5 Kohms. FYI

Many times they are the same basic parts but the bike model changes makes the spark wires longer, or the bracket different, and so they change numbers for that newer model.

So I looked at the fiche for the 2010 VTX1300 and it actually uses one of each. I still haven't been able to figure out the difference other than the color, the MCC one is green and the MM8 is black. In the part description below there is an obvious price difference and the one my bike takes per Honda is the one that has (TEC) at the end. I actually have 2 sets of 1300 coils coming I got really cheap so I will end up with 2 of each part number. When they get here I am going to compare the ohm readings and see if there is any difference. It seems to me that since they still manufacture them and they are still currently used (1 of each part number) on the 2019 VTX1300 there has to be some sort of reason, plus the price difference.

So far it looks like 1987-2000 the 1100's use 2 of the MM8 coils. 2001-07 they use 2 of the MCC coils. The VTX1300 uses 2 of the MCC coils 2003-09 and 1 of each 2010 and later. I will update as I figure more out. The coils should be here next week.

COIL, IGNITION 30510-MCC-003 $57.99

COIL, IGNITION (TEC) 30510-MM8-003 $72.30

I would think they are both made by TEC as the -003 part of the number is the same.
At least based on my understanding of the usual Honda part number breakdown.

It will be interesting to see what difference you find in the parts.
