Very nice and detailed DIY! Great post.
Quick question though, I didn't see anything mentioned about measuring the spark plug gap. Did you measure the gap and adjust or just install them as is out of the box?

Thanks, Lawrence!
I just followed your DIY step-by-step and replaced the spark plugs in my '05 525i. Your DIY was extremely helpful to someone like myself who has never done any sort of engine work short of changing fluids, much less spark plugs. I opted to replace the spark plugs with OE Bosch ($6-7 each shipped from autoanything.com) since I've read about reduced longevity in some of the higher performance iridium plugs. I noticed that a couple of the 13mm plastic bolts must've already been broken by the mechanic at the dealer since they were missing. Oh well, everything is still held in place tightly. I replaced mine at 60,000 miles as well...the plugs looked very similar to the pics you posted. I haven't noticed any sort of performance gains yet, but we'll see if my fuel economy increases 1-2 mpg. The whole project took about 70 minutes (3 beers) but I was really putzing around and taking my time.
thanks again!
