new spark-plug
 

Hi guys,i'd just replaced the spark-plugs on my 08 3.0si at 68,500 miles. Pretty easy to do, and boys does it run smooth now,that n52' purr like a kitten. Just want to share thanks.

Were your old ones THAT bad? Perhaps the placebo effect has taken you...

what kind of spark plugs did you buy?

NGK-R although the oem were Bosch.

I cannot tell how bad they were,it's for peace of mind i guess.

...? You said it runs smooth now, implying that it didn't before. Am I missing something?

You are'nt i'm just happy.

So your original post, about how the vehicle runs "smooth now" and that it "purr[s] like a kitten" was just simply based of nothing?

Is the a DIY out there for this? I want to see what I am getting myself into.

If I'm reading this thread right what your after is peace of mind.
That being the case just have a nice glass of wine and you'll get
the same euphoria with a lot less work, less money, and less
time spent.....:D
