Updating this old thread.
Getting ready to order a set of new spark plugs, and was wondering if there's been any recent brand or model number changes or updates since the date of this posting?
What's your current favorite plug?
Thanks - DM

Beru, for this application(IE Boxster). Bosch are terrible, foul easy, poor quality(made in china, most of them except some oldies). NGK are not bad, but I don't think they have the heat range quite as nice as Beru, who also makes the coils. The detonation quality seems to be the best off these. Good luck with it.
Regards

+1 Beru all the way..
When you've lost engines due to Bosch plugs coming apart? You'll stop using them.

I put in NGK Iridiums last spring replacing the Beru that were in the car and the performance improved nicely.

Hum, my packages say there are made in Germany.
I've had 2 sets in my Boxster S with no issues. Set that was in the car when I bought it, set I put in 2 years ago when I replaced some cracked ignition coils. I found some more ignition coils cracked this summer and replaced all 6 with some APOL "Performance" ignition coils along with new plugs since I had access to them.

Interesting, the one's I've gotten were made in china and the detonation quality was terrible. I've tried them all, as we have multiple 986's in the family. The 01 we have came with Beru's when new and we're still on all the original coils, no cracks or misfires.
Having said that, I'm about to try a set of china made Bosch injectors in one of the cars. So, I'm interested to see how they are.

Last spring I was changing the plugs in about 10 of my ( old and depreciated) cars, Porsche, Audi, VW. After doing some searching I ended up getting Denso Platinum TT 4504 (PK20TT) "Made in Japan". Lots of them, going into a wide range of engines. There was not an increase of 10 HP per plug, and I didn't get 50 miles more per tank of gas, but nothing has blown up and everything still runs smooth.
I'm still fairly simple when it comes to maintaining cars, so I'll call the them my current favorite: Versatile, not silly expensive, cars run smooth and engines don't blow up.
