Spark plug OEM BMW or Denso
The DENSO spark plugs are 6 for $23 at walmart. These get great fuel economy , smooth idle, Great Power.
Pros: great fuel economy
Have some I'm waiting to try out in my turbo 4age after using bkr7e ngks for years. I mean denso is an A1 company and they offer heat ranges colder than NGK so probably worthwhile for my turbo engine.
Pros: colder heat ranges

I bought the plugs from Toyota (Denso). I asked for the old plugs off. The plugs I got back were NGKs that were installed at the factory. I can’t say I notice a difference really (except new plugs did seem to make a difference).
Pros: new plugs made difference
Cons: no noticeable difference
Vehicle:
Toyota

Part number: 4511
