: Which MSD coil....

12-07-06, 09:05 AM
Reguarding the MSD red coils... They seem to make two
that fit the LS6 engine. A part number #8245 and #8246.
Would anyone happen to know which one will direct fit my
2004 LS6 cts-v.

I tried looking through there site but I can't find a difference. I'll call my local speed shop tomorrow to see if they can tell me what the difference is.

i beleave 8245 is for the individualk coil and 8246 is for the full set (8 coils)

Thanks.. but according to the website... It is #8245 and #8246 for either LS6 coil individualy, and #8245(8) and #8246(8) for the complete kit. #8245 and #8246 are completley different looking, except for being both red in color. From the photo(s) i posted, and from looking at your "V" (noticing where the MSD logo is), i'd say it's the 8245(8) for the whole set. Thanks...

Thanks... That's confirms it.. hey.. What are your thoughts after the installation of the coils.. Did you experiance quicker starts, and smoother acceleration.

Nice... Just what i was looking to get out of it. I had the MSD 6A multiple discharge box in my 1966 Pontiac GTO, and the difference in throttle smoothness was night and day. It really helped out alot. Especialy since i had the three carb option (tri-power) on it. :)

Finally, I got a really good deal on them... right before the price went up from MSD. I should have them (#8245) in a few days from now. Any recomendations about the spark plugs.... Should i leave the stock 14,000-mile ones alone, or replace them with another brand and widen the gap? Do i need a colder plug? I'm not running a maggie, or nitros. Just curious to know if the factory plug/heat range is good enough to handle the extra juice. :)

I'm curios about plugs and gap too. I just got a deal on some NGK iridium plugs but they say they are 2 heat ranges colder. I'm Maggied now with stock plugs. Will these plugs work and if so do I experiment with a larger gap??

With the Maggie you should go one range colder than stock, NGK 55 iridiums gapped at .40

not to hijack this topic but I have a brand new set (8) of 8245s if anyone is interested. They were going to be used for another project but I went with a different ignitial setup. $480 or b/o

I also have the wure harnesses if anyone needs them
