I need to put a set of plugs in my 251,000 mile X5 3.0L. It was some
100,000 miles ago that I last replaced plugs and I can't remember which ones I used. Seems like it was the 4 ground NGK BKR6EQUP ones.
Sparkplugs.com has 'em at $8.48 each. I seem to recall that Autozone has them for about $7

Input please!

BTW, the latest repair on my chariot was the replacement of the fuel pump and relay for $666.41 today. The fuel pump alone was $405!
