How often do you have to replays set of spark plugs ??

Brand New Set of Platinum 4 Electrode Spark Plugs .One set is required for 8 cylinder spark plug job. Made by: BOSCH


eBay Motors: BMW E52 E53 X5 Z8 V8 - Platinum Spark Plug Set (item 390044653652 end time May-15-09 22:00:57 PDT) (ebay find)
regards :dunno:

There is no need to replace them at 52K unless you have faulty plugs. Are you noticing hesitation or something?

And when you do, buy the plugs from BMW.

And don't use Bosch. NGK or Denso (iridium, etc.) please.

I believe BMW specs Bosch and NGK for the X5.

X5 (E53) M62TU, M54 All - NGK BKR6EQUP

X5 (E53) N62 - NGK BKR6EQUP or Bosch FGR7DQP

Unless Bosch has improved quite a bit, they are an iffy proposition for a BMW in my experience. Problems seem to follow their installation into a BMW. Hesitation, starting issues, etc. :dunno:

I prefer the Denso iridiums, myself, but I'm a gearhead. I go so far as to index the plugs in every car, not just the race car. It only takes a few more minutes to find the right plug/cylinder combo so I do.

:Dthank you all !
no , there is no unusual sounds (or feeling of foulty pl.gs)..tipical working engine sound..( I like it on freeway! mrrmrmr)
I did, thought, "dillers" might be more..likelly backed up package/perchase.
New better , then old ones ,but probably is not in all situations.
best regards

:wow: I might have just found the worst speller....yup..I did.

Give him a break, just check out his avatar, he's like 175 years old. Not bad if you ask me. I'll probably be drooling all over myself when I hit 90.
