Spark plug OEM BMW or Denso
OEM are actually cheaper than a lot of aftermarket plugs. Buy from a place like bell Lexus or just get the denso branded equivalent. They last hundreds of thousands of miles in some cases, so OE has certainly proved its worth
Pros: last hundreds of thousands miles
Cons: cheaper aftermarket plugs
Vehicle:
Lexus
Denso 3297 on Rockauto are the Oem plugs
Part number: 3297
I bought my 2019 330i in 2022. It was a lease return. While basic maintenance items are a lot more than, let’s say, a Toyota, it has been far from a money pit. I have put 50k miles on it in the three years I’ve had it, and had nothing out of the ordinary go wrong. Spark plugs, brake pads, air filters, tires, oil changes, that’s it.
Pros: nothing out of ordinary
Cons: maintenance items pricey
Vehicle:
BMW
Mileage: 80467 km
There is no risk, EQT specifically recommends them. Been running denso 5749s for over 40k miles and change them every 10k. Send it.
Pros: EQT specifically recommends
Vehicle:
Volkswagen
Mileage: 40000 km
Part number: 5749S
Ive been running eBay denso plugs for 4 plug changes. You need to read reviews and look at the packaging to make sure they're not counterfeit. They've lasted me and performed exactly as they should.
Pros: lasted and performed
Vehicle:
Toyota
It is, I have a 2020 330xi with 80k miles. It runs like a champ. Make sure you change out spark plugs. Most people don't. NGK's come with the car.
Pros: runs like a champ
Cons: spark plugs
Vehicle:
BMW
Mileage: 128748 km
I have a 2012 Civic LX (purchased new) and replaced the original spark plugs at 100k miles with **Denso 3483 (DXU22HCR-D11S)**—which were listed as compatible on RockAuto at the time. I’ve had great results and am now at 200k miles, looking to replace them with the same.
Pros: great results
I replaced the plugs with DENSO 5358 roughly 10K miles ago.
Mileage: 16093 km
Part number: 5358
The previous owner had installed some Denso IKH24's that looked..... disgusting. In fact, I have NO CLUE how the car ran as well as it did, as the tips from the Denso plugs were gone, and the gap was 0.055. The car still had a slight miss after I did the coils last month which prompted me to replace the plugs.
Cons: disgusting appearance, tips gone, wide gap, slight miss
Vehicle:
Kia
Part number: IKH24
Ive got the densos twin tips in a vxr at present. One thing i can tell you is they dont like heat!!! i recently had a small coolant leak and they would misfire. pretty low heat resitance i think. work fine on cooler engines.
Pros: work fine cooler engines
Cons: dont like heat, misfire
