Beru or NGK

[dezpimpdada]

so i recently replaced my spark plugs at 60k ( which fixed the idle problem), i really wanted to go with the NGK laser iridium especially after seeing the OE Beru ultra ( not platinum). it puzzles me why no platinum plugs for the car, however i stayed with the OE just to be safe.

but it still bugs me if that was my only option to go with OE or that the NGK's are actually better, i have asked serveral mechanics and everyone holds differrent opinion, except all porsche dealer guys say to stay OE.......figures~

anyone with experiences using after market plugs?

WTF....Plugs is plugs, they all spark and the internal combustion engine has not changed a great deal from Otto's days, they all go suck, squeeze, bang, puff

Anything within heat range is good :rolleyes:

Actually I totally disagree with Glvn..

Iridium plugs seem to work better in some cars than others. My dad's race car has a terrible time with iridium plugs with mis-firing and fouling. Runs great on regular NGK copper plugs. Anybody running a turbo car will find that platinum run terrible as well, some have luck with iridium and others with regular copper. Nitrous cars can only run copper, nothing else.

Seems that platinum and iridium are prone to developing hot spots on the plugs and in different applications they cause the car to detonate pretty badly.. I did the plugs in my Jetta VR6 (daily driver) and just went with some regular ol plugs and it ran like crap. Went to the dealership and got the Bosch silber plugs they recommend and it was so much better.

I would have though the same thing as you Glyn, however after some years of racing and having different plugs not work at all for me you either run OEM plugs or something specific to your engines setup that you have tested and figured out to work on your own or something that somebody else has done so with a similar setup.
