BERU spark plugs

Hi guys, I have just bought new spark plugs for my Boxster 2.5 1999. The person in a shop recommended BERU Ultra-X (4 ground electrodes - UXF 79). Are they the right plugs or do I have to have just with 2 ground electrodes? Thank you for your help!

The stock/OEM plugs on my 2000 Boxster S were Beru with 4 electrodes. That's what I bought to also replace them. Not sure on the part number or the "Ultra-X" part, but it sounds like you got the right part.

I just put the Beru Ultra-X 4 electrode on my car. Was shocked at $14 per plug. Can't see how they are worth that much more over the Boschs

Use factory Beru plugs..... 2 electrodes

The engine was designed for 2 electrode type Beru plugs. Buying the 4 style is a waste of money. While the Bosch might be cheaper, I HIGHLY recommend the Beru ones. Any other plug won't be optimal.

Don't pay twelve bucks

The four prong plugs are around six dollars at ************************************************************ and are listed as OE. I don't know about the OE part, but six bucks each shipped to your door is a good deal.

On my airplane we have no choice but to use two prong plugs, and I can tell you getting them gapped so they fire on both sides is tough to do, and in practice only one prong fires. Four would improve the odds of getting multiple spark. I'm changing mine in the S this weekend, having ordered from ********************************az.
