Changed the spark plugs

aakrusen · 07-09-2019, 09:08 AM

Recently changed the plugs, roughly 80k miles since they were changed last.

Prolly best to not do that again... (not sure if the attached image shows up - highlights the 37K mile spark plug change interval recommendation from BMW)

Car run better now?

Wow.. those looked pretty bad!

aakrusen · 07-09-2019, 12:37 PM

I purchased the car a month ago w/ 132k miles. I have all the service records from the previous 3 owners, and the last time they were done was around 80k miles ago. I’m going through and replacing various wear parts while I wait for my Rod bearing kit (the BE spec’d Rod bolts are on back order). Might do the rear diff fluid this weekend while I continue to wait.

Mine showed a visibly increased gap at about 30k.

Bmw in Spain change every 20.000 kilometers

roastbeef · 07-10-2019, 12:38 AM

damn. no misfires?

aakrusen · 07-10-2019, 07:58 AM

I had only put about 200 miles on the car before I changed the plugs. No misfires or codes thrown. I didn't get enough seat time in this car to notice a difference in how it ran as I've been taking it easy until I can get the Rod Bearings done. The only reason why I changed them is because I could see from the service records that it has been a long time and I know these cars like to have new plugs. Glad I did, I've never had plugs look this bad.

Just found this post exactly what I needed to see. Mine has 87k miles supposing never been replaced.. do you have OEM part number by chance? How difficult of a job was it 1-10? I’ve got all the tools besides the coil pack removal tool.

It's a 2 out of 10 and the coat hanger trick works like a charm.

Your coils thank you...

Mine popped out real easy with a flathead with finger support. That being said, there were a couple "oh shit" moments near the back...

Also, I saw a lot of DIYs that have you take off the plenum which isn't necessary.

pbonsalb · 08-24-2019, 08:25 AM

I broke the plastic top off one of my rear coils. I moved that one to the front.

I saw a couple of those too? Entirely unnecessary and it's hard to get those rubber couplings reseated on the ITBs.

Just the intake elbow (+airbox for better clearance). I used a coat hanger and had it done in 45 mins.
