Spark plug Bosch or NGK

I just replaced all 4 spark plugs on my car @ 114k miles. Now I’m so glad I did it because the car feels way more peppy and responsive.

I have a N55, e93 And went through the same back and forth between NGK and Bosch. My car is 100% stock. Ordered ZR5TPP33 Spark Plug - Bosch and the car runs just fine.

My F15 had the Bosch ZR5TPP33-S from the factory. I replaced with ZR5TPP33 when doing the valve cover about 20K miles ago, and no problems so far.

I upgraded to NGK Iridium spark plug in my classic 500, 2 years ago. There were minor but good changes in performance.

The fuel economy increased a bit and the self starts have been better.

NGK, used them for years in multiple cars. Seem to last longer, but I have no proof.

New NGK plugs this summer and she\u2019s still purring away (and snarling when I drop the hammer). Honestly its one of the best motors ever to come from Honda and I\u2019ve loved both of mine.

I don't use spark plugs like that unless the vehicle specifically specs for them. We used to put Bosch W7DTC's in these, or at a minimum, just the single electrode version.

They run just fine on stock setup. Changed mine 6 months ago once the car was at 30k miles and actually managed to snap one of the plugs in the head ???? Carefully managed to get it out though. No noticeable difference from factory plugs.

Please use original plugs for the replacements. Just yanked out aftermarket NGK platinums because of a misfire. For some reason, Mazda and aftermarket plugs in my experience always resulted in a misfire.

I changed the plugs on my 2017 raptor recently with NGK iridium plugs. The punchline is that the truck started backfiring when I pushed it. I ended up putting Motorcraft plugs in and it cleared up.
