Finally did this today and it was incredibly easy with this DIY. The factory NGKs looked pretty worn at 71k. Replaced with NGKs.

Thanks!

Great post, this was my first time doing spark plugs and this made it very easy for me. All the pictures were very helpful. I went with the bosch platinum +4 just because thats what autozone had. The idle is smoother and the car tacs up much better.

Thanks

Question Tss330

AS i'M NEW TO THE BMW WORLD i'M JUST TRYING TO FIGURE WHAT IS REALLY NEEDED IN THE WAY OF SERVICING AND WHAT ISN'T ...the '04 330 Ci HAS 58000 km(35000 Mi) on it. Next thing is Oil Service, but, at this stage do I really need to do anything else?

Have you had your Inspection I done? It is basically a glorified oil change. The dealer should cover that if you're still under warranty and under 50k miles. If not, it is easy to DIY: just change the oil, oil filter and cabin air filter element, top off all other fluids and do the visual inspections. Here's a checklist:

Also, if you are still under 50k and under warranty, the dealer should flush your brake fluid every 2 years. If it was my car, I would also change the engine air filter element, wiper blades and coolant.

No anti-seize on a steel plug going into an aluminum head ?!? Are they perhaps trying to create a new revenue stream selling replacement cylinder heads?

BTW, in case you don't want to use anti-seize per se, an old mechanic's trick I learned from my Dad: moisten the threads with a drop or two of clean engine oil, then dust a puff of graphite powder on them. Oil will be squeezed/burned off, but the graphite remains and lubricates when taking the plug out again.

At 56k miles, I just replaced my spark plugs. if it wasn't for your awesome DIY and other supporting comments on this thread, i wouldn't have had the guts to tear into my engine bay. I would post some pictures up, but am embarrassed at how dirty my engine bay is! My spark plugs were just a dirty too. My son-in-law the mechanic helped out which was comforting and cool to have his tools at the ready. And, I did most of the work too! This almost completes my full Inspection II. Still need to get the fuel filter done. Will probably take it to a shop for that one.

I do have one question, when peering down the spark plug hole, the top of the cylinder was visible and it was fairly black with carbon.

I only have put super unleaded in my car but, haven't used any of the fuel system cleaners etc. Any suggestions on products to help this condition (if any?).

Thanks again!!!

Johnny

You know, I just came back from a test drive and I KNEW someone was going to come up with that! LOL! I may not have it bumping off redline for hours at a time, but I get up there fairly regularly. I have a 30 minute commute with some quick spurts, especially on the way home when I have to fight that 680/24 interchange in WC!

Oh, and I enjoyed responsibly. It was a Clausthaler fom Germany.

In all honesty, don't worry about the color you see. Doesn't mean a whole lot.

I almost felt like getting a long Q-top and detailing the piston tops... Just kidding. I don't have it THAT bad!

Oh, one small tip. When you're replacing the top covers, don't press too hard on the little bolt cover thingies. The plastic holder in place thingies are fragile and will break off. So, it's off to the dealership for a very expensive little piece of plastic. I just hope they sell them separately. I don't want to buy an entire engine cover thingy just for that!

Its funny, I just changed my spark plugs this afternoon and this thread comes back from the dead. It took me about an hour, I wasn't in any rush. My car has 60K miles and the plugs looked good, it almost was a shame to replace them.

Tomorrow its the CAB's and then the cooling system.

Dude! How goes it in the South Bay? I grew up in Gardena. Used to love to go to a place called The Burnt Tortilla on Western. Moved up to Northern Cal in 1983.

Can't complain about the South Bay, it was 80 deg yesterday, it suppose to be in the mid 70's today and it suppose to rain tonight.

The Burnt Tortilla is great, maybe I'll cruse over there after I finish with the CAB's.

KrisL, another helpful post. I'll be changing my plugs this weekend. One question though. It's been a long time since I've changed plugs on any car. You didn't mention having to check/set the gap on the plugs? Are they already set when you get them now? Thanks!

Changed plugs still running rough....coils and cylinders

KRISL, man great. I just changed my plugs after wrestling over whether or not i can do it and it was like butter. Great instructions to the mechanical terrified to break something.

Now that i have done that the ride still runs a lot rougher, shakes and vibrations. When i change the plugs (E46 1999 323i) there were 3 out of the 6 spark plug socket covers that pratically did not have to use any effort to pull off and 3 that i really had to use a little mojo to get off. The three that need little effort, do they need to be replaced or is that how they are suppose to fit. the spring coil inside looked flat vs the others.

I feel like i am close to getting my baby back running properly without having to spend a lot of money at the dealer or independent. Do you think you have any advice on helping with this?

Thank you sir! I look forward to hearing from you!

You say the car "still" runs rough - was it running rough before you did this?

The coils should be snug on the spark plugs... do you have a check engine light? If there is any spark plug misfire, the light should be on, and with a simple code reader you can identify the problem..

KrisL inspection II spark plugs DIY

KrisL,

I have a 2003 325i

That was an awesome post, followed your method, to the letter it was great. The photos make it all gel. Took my time and it went smooth. My coil cover popped up by finger 90 degees to the engine orientation, to the right, towards the drivers side. After completing called to check for an estimate, dealer ship $340.00 I'm sure an indy shop would be cheaper, but it sure makes you feel good when it all comes together. Thanks again.

DIY Spark plugs

Hello everyone. I am going to change my spark plugs on my E46 in the next couple of days. I wanted to know if there is something else I should do in the area while I am at it. I am going to also change the cabin filter. Any insight or recommendations would be appreciated. thanks
