To change or not to change spark plugs (yet)?
Quote:
In the end, I just got a brake flush and oil change for my 6th oil change service (Year 5). Previous owner changed spark plugs under warranty at 22k miles on third oil change (Year 2). Should I get my spark plugs replaced now, or wait until I hit a certain mileage? It only has 20k miles on it after 3 years and has seen zero track days. Suggestions appreciated! |

Did they say what constitutes "value oil" vs "regular oil"? |

I just DIY'd the plugs on my F80 for about $72 for the sparks from FCP and $35 worth of tools that I was missing (tools have become expensive lately, specially the e-torx socket sets)

It's robbery. Worst part is they say it's 5 hours Labour and they have to video everything "in case your engine goes bang" when you drive down the road!! How reassuring |

Question for those that are buying the NGK 97506.
Are y'all adjusting the gap on those or just installing as is? There's a lot of different posts about different gaps for different mods/maps but I'm just running stock no performance modifications. Also I've done the sparkplug and coilpack replacement myself in my apartment garage with pretty basic tools. It only took forever but I was able to button it all up and had no issues but I just ran the OEM plugs. |

I just did mine recently along with new coils, took me probably 3 hours total. Definitely a lot of work, but the only "specialty" tool I needed was the spark plug socket. The E-torx can be used like normal with a proper 6pt socket. I think I used 10mm and 11mm 6pt 3/8 sockets for the torx on the aluminum brace. Easy peasy.

I'm running the Bosch plugs, checked the gap out the box and they were all 0.28". Bone stock F80 so I felt no need to tighten it up.

Yea I can agree with you on the DIY portion. Definitely more time than difficulty. I ran the Bosch plugs but the general consensus seems people favor the NGKs so I didn't know if they needed to be re-gapped but I guess I can use 0.28" as default and regap to that if needed. Appreciate ya

I always check my own gaps regardless of vendor. OEM plugs are usually properly gapped at 0.028" but we've seen 0.025-0.032" out of the box.
For any other plug (NGK or F8S) a check and gapping is mandatory. Those plugs usually have wide gaps because it's easier to "gap down" with feeler gauges and a ground strap pusher (screw in the plug, insert feeler, tighten screw to push ground strap to 0.021-0.023"). Trying to open up a gap usually scratches the iridium on the ground plate, and few of us have a proper gap opener tool (like a tiny tree, branches at different thickness to grab a strap in the middle). Plug change is easy. Remember to tighten to 25Nm for proper washer crush.
