Anyone here buy a spare and keep it in the trunk? I’m debating between buying all 8 or just two. It’s really not a big deal to keep a 10mm and a torx in the car. Along with a cheap obdii dongle of course to isolate the misfiring cylinder on the fly.

I keep two in my trunk. I’m considering throwing them in a food saver bag with a desiccant pouch and pulling a light vacuum for storage in there.

I recently purchased an “OEM ignition service kit” from turner for $850 which come to find out includes aftermarket standard motor parts ignition coils. They look like cheap parts store ignition coils and are being returned.

I ended up purchasing 5 good used ignition coils from someone locally today for $100. I am going to put four of them in the rear of the engine and keep my 204k mile ignition coils as spares in the trunk.

I have heard reports of the original ignition coils lasting 200-240k miles without issues. All of my ignition coils are original and the car runs great. Anyone pushing 200k I would recommend just purchasing a used set of ignition coils from a sub 100k car.

There is no way of telling when they will fail. When they do, buy a new OEM coil. Mine failed at 65K (only 1) so far.

Does anyone know if any changes to the production quality of the NGK 48729 coil? This is a 2022 edition thread. I had 1 fail last week, car has just over 100k miles, its an '08. BTW that failed coil I glued back together (top snapped off) 4 years ago and has been fine since. Guess I'm asking is it a hit and miss with the NGK? 1 in 10 are bad? or all bad? From the thread it appears all are junk.

Anyone know if any good (NGK) aftermarket versions made it back into production? Few of the other options failed immediately on me. I heard NGK stopped making them for this engine (fingers crossed).

I don’t think anything has changed… still. All aftermarket are garbage. Just find a good used set in case of emergency or spend the $$$ on new ones from BMW!

Found a 3rd party on Amazon. Haven’t tried it yet as i still have an oen backup sitting in my trunk. But for this price someone might want to try them out. Just let us know if they are any good please. I’d buy a full set of 8 just to keep in stock if they work.
