Spark Plugs -- What a difference!
 

I just changed my spark plugs on my '02 3.0 at 70k-- huge difference! After STF I picked up some NGKBKR6EQUP at my local auto parts store for $7.99/each. I had matched up the original plugs with the new ones are every mark/stamp is identical other than the BMW print on the plug. After spending $50 and 45min -- the X5 is running like a new car.

For those who are looking for what tools you need:

5/8 spark plug socket -- Sears has one for $5
socket wrench
6 inch socket wrench extension
10mm socket for the hex bolts
flat-head screw driver to help unlock metal bracket on coil
TLC / Patience

It is pretty easy to do but the furthest plug near the firewall gave me a bit of a challenge.

I wouldn't go 100k without changing the spark plugs. Since I will be keeping this X5 for awhile, I will be proactive and changing them every 25k-30k miles.

Next steps? Gonna change the oil (when my car hits 7k miles since BMW dealer changed it) before the regular intervals of the BMW maintenance.

HA, my car has 60K and I did the spark plugs last weekend too after I read another thread. I also had the oil change from the dealer ($110) yesterday and replaced the air filter ($24) myself. The car is running so much better now. :thumbup:

Only thing is Advanced Auto Part sold me the NGK plug BKR6EIX instead of the OEM one. They look totally difference but when I look at the NGK site, it says they should be higher grading plugs.

Anyway, the car is pulling much stronger now than before and I am happy about it.

Very nice! My local auto part store had both the OEM and the Iridium version that you have -- I ended up just sticking with OEM. Maybe I will try the Iridium on the next spark plug change.

What kind of air filter did you buy?

$110 for an oil change?? Holy @#$&

The air filter is an OEM from the STEALER
