Couple of failed Ignition Coils and my Indy shop is having trouble sourcing replacements.... where do you guys buy them online. Bimmerzone doesn't seem to have any for the '06 M5.

Help ASAP would be great.

Pulling this back up, is the coil made by Standard Motor Products the OEM equivalent? I bought one off eBay but I wasn't sure if it was a genuine OEM replacement. I just got it and it looks pretty much identical to the original. The only difference I can see is the original says "Era Power Train" on the rubber boot and the replacement says "Pulse Power Train". I also bought a couple from getbmwparts.com because they just listed them as OEM replacement but they're $15 more per coil pack. They haven't shipped yet so if they're the same I'm going to cancel the order from getbmwparts.com.

I replaced all 10 in my 2008 M5 when 1 was going bad 140k miles and I noticed an immediate improvement in low end torque.

While you're there I would change them all out and replace all plugs.

I just got my "genuine OEM" coils from getbmwparts.com and they are identical to the ones I got from eBay, made by Standard Motor Products. They're also the same ones on RockAuto Parts Catalog for $46. So if you need coils I'd get them from RockAuto Parts Catalog and save yourself some cash.

Just want to give everyone a heads up. I bought a set of 10 ignition coils from the bmw dealer here and it turns out, they are the exact same part as what the autoparts store sells. Same part number/markings..100%. The parts store sells them at $55 vs $112 at the dealer.

This just goes to show that one needs to be careful...if funds are not free-flowing !.....when buying parts from the dealers.

But...a word of caution.

I have a good friend who owns a specialist tuning/repair business in the U.K. He previously was with Ford/Aston Martin and he categorically states that although the parts may look the same to the untrained eye there are minute differences.

I have come to believe this assertion based on my experience with suspensions.....with the roads we have here suspension components are consumables for me.

A case in point are the tie-rod's for the E39......although Lemforder produces these parts for BMW and they look identical to the BMW original there are differences. You'll also notice that with the Lemforder tie rods the turning circle of the car increases ever so slightly.

We had a long discussion concerning this issue on the E34 M5 Board several years ago.

Personally, I buy almost all of my electrical components from BMW while I mix up the suspension components due to the high wear rate.

Cheers

Sorry to revive this thread.....

I'm looking for a place to get coils for cheaper, at Rockauto they are at $71. Any place cheaper than that OEM replacements? My Indy mechanic says my coils are shot since car is throwing codes of misfire in every cylinder.

I bought one from oreilly auto parts at $55. It turns out that BMW sells the exact part at $140. The old ones on my car were bremi, made in Germany. The new one from BMW..made in China.

I researched a bit more and invested in the ionic modules, changed them myself, took me two hours in the heat! No codes anymore and no "reduced power", cost me about $500 from the local stealer
