does bmw 435i fbo E30 require 1-step colder plugs?
Hi, I have a 435i 8AT with the following mods...
Wagner tuning catless DP & evo intercooler supersprint cat-back exhaust Quaiffe LSD bms air intake (mostly for the dramatic sound) alu chargepipe Im running those mods with a wedge performance E30 tune. Would it make a difference for the better or worse (and why) for me to go with for example link 1 or link 2 Car goes great as is, I'm just asking preemptively. |

I run OEM plugs with E30 on MHD stage 2+ with FBO (and more) mods with no problems. |

I have looked through a couple forums, without really finding out why to get the or why you shouldn't get the spark plugs (the pros and cons with them). Which is why I asked again. But no worries, thanks for clarifying again. |

Pros: Potential to eliminate misfires / "spark blowout" at very high boost levels with smaller gap, but again, 99% of people don't need this. Pros of stock plugs stock gap: You want the biggest gap possible (without issues) so you start here. That gives you the best combustion. Cons: None, unless you start getting misfires. |

if the stock spark plugs are new, you'll be fine. As they get older they start misfiring and that's when you need to upgrade to the NGK colder plugs
