Found them in the Mercedes S550 and they are new so no need to replace, but wondering why they used a chain store brand. I see they cost $68 each when Denso would have been half that. On the other hand, they splurged on NGK Rhutenium plugs.
Are these Duralast coils any good?
- Thread starter atikovi
- Start date
I would've preferred a Bosch part on a German car
Don't expect them to last forever, but I don't have any personal experience with them
I've not had the best luck with parts store house brand electrical parts in general

I love how each coil has 2 hold down screws.
My lowly Volvo has only one.

German belt AND suspenders mentality.
Just because they're new doesn't mean they won't need to be replaced 
I wonder if the boots were torn when someone attempted to replace the spark plugs.
They come with the boots.
Exactly. So I wonder if someone tore the boots on the original coils, and instead of sourcing new boots, they replaced the coils.
A small note on my COP experience over 20 years of Volvo "white engine" (5 cylinder) ownership.
Before my first sparky-poo change I feared brittle wires on the coils.
I called an online Volvo parts dealer in Texas and the fellow said, "We stock 'em and I've never sold one".
In a related vein, posters on Volvo boards claimed the coils went out, "all the time".
I've never needed one. (of course, now they'll break)
As far as those boots go, sometimes they're featured as sale items; another example of something I'd insist be OEM.
Uro spark coil boots? No thank you.

If it's running fine I wouldn't touch them but in general, I'm an OE coils and OE plugs kind of person, or at least coils and plugs made by the same OEM as the OE, generally on Eurotrash it's all Bosch.
Dealer only for plugs. Not even Bosch aftermarket for euro.
That's asking for problems
I’ve used one on a Honda crv, and one on a jeep Cherokee. Did what they were supposed to do
Is this from personal experience?
Not something I would want on my engine, going down the el cheapo parts rabbit hole is one of the reasons for German/Euro cars getting a bad rep. Bosch or OE, OE from ECS are about $60.
FCP Euro!
Wait - you bought the car because it has 22” wheels, and you want to “fix” it with non OEM drilled rear rotors and big box store transmission fluid that does not meet spec…
But you are wondering why somebody used chain store parts on the engine???

They are fine as a many others but sometimes other retailers have different brands the other may not offer. You have to shop.
Interesting. I just tuned up a 2014 BMW M6 at 56k miles while it was here for CIC unit repairs (BMW lists 60k mile plug replacement). I used the same Bosch number as what came out of the car - Autozone stocked them and they appeared to be the exact plug by visual check except it didn't have the M logo - but same everything else even the engraved part numbers were identical. Car runs great -are you saying these plugs were not acceptable to use because I've used them in the last 10-15 BMW's I have serviced so I don't want a bunch of comebacks.
