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.
