spark plug change experience
 

Just changed the spark plugs on my 06 4.4i this weekend.
With only 70K miles on the clock - the X drove fine before but whoa - after the plug change, its much peppier and flies now.

Plugs were obviously original NGK and were used up, no oil or any nasty material, just plain worn. Got new plugs from advanced auto - 6.99 a piece, same ngk model and part number, but no BMW logo saving me tons of cash. Straight up took me under an hour, back 2 boots right hand side were a PITA to get out thanks to the coolant hose, but managed it without an issue.

The most simple DIY i've ever done in any vehicle! Time to relax now. Money well spent. Also did not use any anti-sieze either, plugs went in easy.

Can you post the part number ? Have the same model/yr, and planning to do it at 60k.
thx

Nice job.

My dealer told me BMW does not supply NGK plugs any longer, only Bosch. Also, keep in mind that your OE plugs had a 100,000 mile change intervals. The plugs you bought are not the same and should be changed every 40,000 to 50,000 now.

Here they are:
BKR6EQUP - NGK
Part No. 3199

Hope this helps!

Do you know what the Bosch part number is used know? I would like to change mine and use the platnium that the factory uses...

Thanks.

Here is a link where you can see the Bosch part numbers for an 06 4.8is. They are listed below hte diagram.

The anti-sieze is not for the plugs going in it is for the next time they are changed coming out.

^ Good point. You aren't lubing them up to get them in. http://www.xoutpost.com/images/smilies/rofl.gif

haha true - indeed

Congrats on getting back some off your lost power. I've been telling people to avoid the overly priced BMW supplied plugs for forever, and this is a testament as to why. Its such an easy job, you could replace them 3-4x over with the Autozone ones and still not be at the cost of one set from the stealership.
