Subject: The dealer list price for either NGK BKR6EQUP or Bosch FGR7DQP (aka 4417) OE Author: stritarja : member since November, 2004 : 1546 posts Posted on: 2008-10-18 21:10:30

lugs is $19.98 each, but as other have said you can get the NK plugs for about $8 each and the Bosch 4417 for about $5 each from many sources. The Bosch Platinum IR Fusion (4503) are also probably fine but I doubt you'd notice any difference from the NGK or Bosch 4417. I had the NGK originally in my 2001 740il and I replaced them with the same at 100K mi.

More important than which of these three plugs you choose, use Permatex copper anti-seize or equivalent on the threads, and torque to 21-23 Nm to make sure the gaskets are fully compressed. The plugs have a tendency to work loose if they are not torqued enough, and you can damage the aluminum head threads if you over-torque them.
