new spark-plug
 

Hi guys,i'd just replaced the spark-plugs on my 08 3.0si at 68,500 miles. Pretty easy to do, and boys does it run smooth now,that n52' purr like a kitten. Just want to share thanks.

Were your old ones THAT bad? Perhaps the placebo effect has taken you...

what kind of spark plugs did you buy?

NGK-R although the oem were Bosch.

I cannot tell how bad they were,it's for peace of mind i guess.

...? You said it runs smooth now, implying that it didn't before. Am I missing something?

You are'nt i'm just happy.

So your original post, about how the vehicle runs "smooth now" and that it "purr[s] like a kitten" was just simply based of nothing?

Is the a DIY out there for this? I want to see what I am getting myself into.

If I'm reading this thread right what your after is peace of mind.
That being the case just have a nice glass of wine and you'll get
the same euphoria with a lot less work, less money, and less
time spent.....:D

...and less bloody knuckles and bruises, I'd imagine.

Thanks OP, doing the same and ordered some NGK - ILZFR6D11 for my 2007 3.0 with 52K. For some reason it says ILZFR6D11 for 2007 and PLZFR6A-11S for 2008+ with same engine?!?!? Plugs are probably pretty worn down by now. I have a E53 as well and hope its just as simple DIY with the E70.

It is. Dont worry if you'd done it on your E53 you'll be able to do it on a E70.

"Worn down plugs" exist? News to me. :dunno:

Dirty or fouled is that better?!?! Is it so hard to believe that YES a BMW combustion engine does need to have it's spark plugs replaced. Why the negative feeling regarding replacing spark plugs? Because its not recommended by BMW or covered under their maintenance plan? I mean for $75 and maybe 30mins, its a pretty good maintenance option?

True! and while you'll do it have a look at the air filter.

One can clean the plugs. They shouldn't foul out unless there's something else wrong. Perhaps people just don't understand spark plugs...?

Why the defensive attitude? Do you know what you're talking about? That is an honest question...or are you just assuming that since they're used for X number of miles, they should be replaced? That logic is true with a lot of items on any vehicle...but not necessarily with spark plugs.

Changing out your plugs because you think they need to be replaced is like changing your lug nuts because you just think they need to be replaced.

Edit to add: changing out spark plugs used to be endorsed by BMW, and was part of their inspection II procedure. Newer engines don't foul plugs out and are much cleaner burning these days. The need for changing spark plugs isn't what it used to be.

Here is replacing your lug nuts what an idiot.

The attitude is for people like you, who doesn't provide any useful info to this thread except for say :dunno: why change spark plugs at all?!?! And the quote of the year should be: "changing sparkplug is like changing lugnuts". We should all have that in our signatures.

That proves what?

Oh, by the way, have you ever cleaned plugs? A cleaned plug works just as well as a fresh one. You must really not understand how spark plugs work...

Ok you are so right, folks should just clean them instead. I am going to drop this as we all can read and see from the above. :thumbup:

My OCD makes me change my plugs every 30,000 miles or so. I like doing the job and thinking that my car is tuned to the best of my ability.

My sentiments exactly, I take pride in doing some easy maintenance jobs on all my cars.

Change your oil, your ATF, etc. Changing spark plugs to gain "pride" is just asinine.

To each their own, though.

No negative about changing spark plugs. It's just that your original post didn't
state any reason for doing so. With that in mind some of us thought your were doing it just for fun. Either way it's your call.

I agree with Quicksilver here. If you just want to do it to spend money and time, by all means, change mine too!

However, the lack of reason shouldn't be covered up by incorrect "reasons."

Changing "Lugnuts?"

That just asinine.

BMW's do not have lugnuts. :stickpoke

Sure but too bad you rather change your lugnuts before changing spark plugs so boohoo to the idiot.:nanana:

QuickSilver, reason was just a simple tuneup didnt think I had justify why? Oil change, air filter and spark plugs but i'll keep in mine to give a reasons why it needs to be done before posting next time.

To to each their own as its "asinine" to change spark plug like changing lug nut. Jermym you are a idiot that thinks oil changes don't need justification but spark plugs does, lololol. Let look at the real problem here, have you ever changed out spark plugs. Maybe the fucktrad can explain to us his experience in changing out spark plugs besides handing his keys over to a technician. LOLOL :stickpoke That is all I got to say about this so you can have your last word like a fucktard I know you are.

Justification not required. However people share their experiences regarding mods, repairs, and various maintainence tips. In the process most folks look for the details. For example I could post "today I changed my tires". And most people round these parts would be waiting for the other shoe to drop. If nothing else is said then the reaction may be "so what? Or maybe others will pull your leg about it. Don't get offended just remember some folks like to poke fun.

FWIW, here's what Mike Miller, the Technical Editor of the BMW CCA Roundel magazine has to say about spark plugs and BMWs:

---------------------------
Spark Plugs

There is no reason to deviate from the factory-recommended Bosch or NGK spark plug specification, changed at 30,000-to-60,000-mile intervals, depending upon the car and severity of service. Basically, any BMW produced after 1993 can easily run 60,000 miles on a set of spark plugs.

The factory also has part numbers and applications for “100,000-mile spark plugs.” These are good too, and are capable of 100,000 miles of service assuming no other problems, which might cause them to foul during that time. However, in engines with spark plugs recessed into the middle of the cylinder head, oil can leak into the spark plug recesses past the valve cover gaskets. This is a hidden leak if the plugs are left in service for an extended period of time, because no one looks in there until they’re changing the plugs or chasing a problem. An oil leak in the spark plug recesses, left to fester, can cause ignition coil failure and even ECU failure. So, even if you want to leave the plugs in service, you should at least check the spark plug recesses for signs of oil leakage at least every 60,000 miles. And at the point you’re in there, you might as well replace the plugs. This is the issue with 100,000-mile plugs.

Moreover, while you may not have any problems running spark plugs for 100,000 miles in some BMWs, this does not mean the plugs will not be worn, or that that wear is not affecting engine performance. In other words, for optimum engine performance, most BMWs want spark plugs every 30,000-to-60,000 miles. M cars except the US specification S50/S52 powered E36 variants want plugs about every 15,000 miles.

Stay away from platinum plugs in BMWs. These don’t last as long as the regular Bosch copper or silver plugs and NGK plus, and have been known to fail in other ways. The regular old Bosch Platinum single electrode plug is, however, a very good choice for cars OTHER THAN BMWs.

:iagree: Now time to research asinine lugnuts!

Your posts are very telling of your character. Because I disagree with you on something, you call me names and insult me? Then you try to make accusations suggesting that I don't do my own work? Perhaps I am not the idiot in this situation.

Totally agree whit you. This guy's an imbecile, when i post this thread he try to screw me instead of bringing something positive!

Tried to screw you? What? I simply asked if your old ones were bad. :confused:

---------------------------
Were your old ones THAT bad? Perhaps the placebo effect has taken you...

...? You said it runs smooth now, implying that it didn't before. Am I missing something?

So your original post, about how the vehicle runs "smooth now" and that it "purr[s] like a kitten" was just simply based of nothing?

Why the defensive attitude? Do you know what you're talking about?...
----------------------------------


Yeah, you "simply asked if your old ones were bad...."

Don't spin when those lines were posted. My original question was around simply trying to understand the reasoning for the replacement. Then, it turned into the OP not having an answer for me, so he got defensive.

When people are wrong, they get defensive.

They certainly do...

Get off your high horse, chief. I haven't been defensive whatsoever throughout this entire thread until this very post. I was not calling anyone names, etc.

Side with whoever you wish, but realize that you're siding with someone who thinks that changing spark plugs makes their motor "purr like a kitten" and become "smooth" when there was no problem in the first place.

:rolleyes:

Jeremy- PM box is full...cannot repl;y re: exteneded warranty.


A

Thanks. Just cleared room.

High horse?

All I did was to agree with what you said.

You said, "When people are wrong, they get defensive."

My entire response was, "They certainly do..."

?

:popcorn: getting exciting:stickpoke:whistle:

Changed them out this weekend. 53K miles and probably on the spark plugs last legs.

The original plug was BOSCH part#FRZNPP332 for my 2007 3.0si. The procedure is a bit different than my 2002 since the ignition coils design was changed. I might write a DIY if folks are interested as I was looking for from my original post before getting side tracked.

They were just about broken in:rofl:

Be careful some people will get VERY angry that you changed your plugs!

I wasn't angry. I was simply stating that some people don't know what the hell they're doing and they replace things that don't need to be replaced.

:thumbup:

Dont worry i do not pay any attention to that kind A_ _ H_ _ _

This thread begs to differ. :D

DIY Sparkplugs
 

OK, can anyone post DIY sparkplug procedure? Mine is 2007 3.0si and 91000mls, dealer said I need to replace my sparkplugs (~$475) and I say "hell no, if so, I will do that myself." I like to get my hand dirty so some help will be appreciated.

The guy who started this thread should be able to provide assistance and hopefully pics; he just replaced his.

I most certainly will myself once the warranty runs out due to the labor charge; plugs aren't too hard to manage.

Sorry guys,i did'nt have any pics or diy but BALX5 may have some, it is not difficult for someone who likes to wrench. To pay the dealer $475 for that is ridiculous my cost was around $100 and it include a new Mahle air filter.

Haven't had the time to do a write-up yet but maybe this weekend. PM if you have specific question in the meantime.

"It's never asinine to change spark plug like lug nuts,we should clean our spark plug as its a waste of money to replace new one, to each their own!!!"

Really? You're still going with that? Hope your X5 is running great! I bet new plugs really help! :rolleyes:

Here you go, my contribution.

Well done Balx5 i'm sure this will help the X5 community. Next time would you please post a DIY on lugnuts replecement. LOL.

Thanks balx5. Good info. If only 4 bolts should be removed that's easy. However, it looks to me removing cowl section (passenger side and center at least) will make my life easier to reach inner two bolts. I think I will replace cabin air filter same time.
