Spark plug BERU or OEM Volkswagen

I use Beru Utra-X UXF79 4 tips plugs. It's a great plug for my chipped B6.

I would call New Dimensions... but I decided to go with the Beru Ultra-X. These have 4 nodes instead of just 1 on the head of the spark plug. They are awesome!

Beru Silverstone all the way....Spendy, but worth it, totally. I have taken the pplugs out a couple of times since I put them in a little more than a year ago, and have found very clean plugs, no fouling at all. the electrodes were in the same shape as when I bought them, hardly worn down at all.
