spark plugs - any preferences?

[Lew]

[QUOTE=Lew;519890]I pulled a Spark plug this AM on my Boxster and see that the Beru plugs were installed from the factory. Looks like they will be in the trash soon. New Beru plugs are coming from Amazon. At 30k the tips are burned away somewhat. The original plugs were made in France, and the new Beru plugs now, come from China.
At Amazon they are priced at $42 today, with free shipping, however I used some of my points on my Amazon Charge card, and the plugs were only $30. A good deal!

Finally got the picture uploaded!

I just purchased Bosch 4417 Platinum 4 electrode plugs. $25 for a set of 6 with free shipping.
I'll post back with results, but I'm sure anything would be an improvement. I scoured through my service records and could find no record of plugs being replaced and it is definitely feeling sluggish lately. 96k miles.

According to the link the same exact plug fits my old E36 323IS

I'd choose whichever brand is on top of the parts stack.

(P.S. I was being sarcastic about all of them being made in China. My point is that there isn't any functional difference so they could conceivably all be made in the same factory)

I got my Beru Plugs today. They were ordered from Amazon, however shipped by EOC Parts in Doral Florida. I plan of contacting them to find out what all they sell. Anyway take a look at this picture....Surprised they were not from China as some have said they would be.
