roughly 39k miles on original plugs

jpsimon · 02-05-2010, 06:14 PM

I have almost 39k very hard driven miles on my original spark plugs. The majority of these miles (read: ~36k) have been modded with at the very least a procede (starting with v2). I haven't ever had any misfires or anything.

/edit/ here are some pics.

Dackz · 02-05-2010, 06:47 PM

Better yet, see the condition of the plugs. How far can we go typically, since I am unmodded and DONT drive it hard most of the time, at 30k, when would I need to change? 50k? Later?

enrita · 02-05-2010, 06:50 PM

yeah see how they looks. You should definetely change them. Thats high mileage when tuned.

TurboSid · 02-05-2010, 07:05 PM

im getting very bad misfiring and im at 22k miles. just got the plugs in going to change them this weekend.

335xiRT1 · 02-05-2010, 07:20 PM

On my first car 335xi i waited till 15K the car was tuned since 1k miles and noticed a big difference,
Now with my 135i I change them every 10K miles, car is being pushed double the stock boost.

yeah I'm changing them either way as a precaution. I'll post pics

blisstik · 02-05-2010, 07:51 PM

I have 35,500 untuned miles, I will probably change them at 42 or next oil change. Why is that socket wrench like $20!?

I'm ordering them right now after reading your post. 18K with no misfires yet, but if it makes that big of a difference I will replace them.

hun77777 · 02-05-2010, 09:46 PM

i just did my spark plugs second time. last time i was at 30k and now i'm at close to 50k (actual mileage since last spark plug replacement is about 18.5k).

the mechanic said
"oh it's not that bad for 50k"
and i said
"it's only been less than 20k since last spark plug change"
and my mechanic goes
"

holly crap that doesn't look good at all then"
so i replied
"yea that's what you get with DI TT engine. according to BMW, it's LIFETIME thing (100k)".
and we both laughed at it... i'll snap a pic tomorrow...

Bagelfast · 02-05-2010, 10:17 PM

Looking forward to the results JP!

Bimmer This · 02-05-2010, 10:22 PM

Maybe I should change mine out. I'm 39K with a occasional misfire during WOT.

zenmaster · 02-05-2010, 11:16 PM

Noticed no difference in performance after plugs where changed @ 50K.

happy4nk8er · 02-06-2010, 01:22 AM

Changed mine at 45k with procede since 12k. I noticed no difference and the plugs that came out actually looked great for the milage.

CubanJJ09 · 02-06-2010, 11:14 AM

il be looking forward to your pictures and review. prob the next piece of maintenance ill do.

vase330 · 02-06-2010, 11:19 AM

Do you guys need to gap the plugs before install or do you just put them in?

I think they have four electrodes, no gapping.

vase330 · 02-06-2010, 02:24 PM

Oh ok thanks.

jpsimon · 02-06-2010, 05:28 PM

that was the easiest job ever! no one should pay to have this done. do it yourselves!

pics to come in a bit

Schn3ll · 02-06-2010, 05:51 PM

I definitely need to do this... 17k on the clock (10k of those tuned), still on original plugs. Jp, let us know if you feel a difference.

Ferre86 · 02-06-2010, 06:41 PM

current plugs have 15k KM on it, and thinking to replace it soon. running all these mods just make sure i do replace it often.
