4.8is sparkplugs
 

I got new plugs for the X5 but I noticed that when I pulled the first plug, the OEMs are a single ground plug. I got NGK BKR6EQUP which is a 4 ground plug... will these work?

Really??? Hmmm... I haven't pulled from my 4.8is yet, but my 4.4 had the 4 prong. One prong suggest you setting the gap, but in the service manual, it states not to gap the plugs. Is the old P/N and new P/N the same?
Where did you order it from?

I just ordered the new ones from Amazon after looking around the forums...

Yea the OEM ones are single ground, double platinum plug that will require gapping.
I had my GF verify that this is the OEM plug at the dealership...she even sent me a picture

I just checked NGK site... looks like I F'd up...:doh:

NGK.com - Vehicle Fitting Results

OEM are either/or
BOSCH Part # FR7KPP332
NGK - IZFR6H11

oi, lol. Well you can return them, right?

Yea, probably...

Yup, you effed up. My NGKs came with a single ground. OE is also single.

Just went to my GF's dealer and picked up the correct plugs. only 80 cents more than Amazon's price and no shipping of course...

Anybody need plugs for a 4.4/4.6? lol

changed my plugs last week, torqued to 18ft/lbs, gapped to 44

oem single prong came out

iridium single prong NGK went in

results = smoother, better low end response/power, mpg+

Yea, The X runs MUCH better now... noticable improvement everywhere. :thumbup:

The old plug color was perfect but the gap was huge... even though the plugs were double platinum, there was still a lot of erosion on the ground and electrode
