Hey Guys anyone tried using the new Bosch Super 4 Spark Plugs They cost about $10 each and I don't know if they do anything to improve performance. Anyone got any tips before I buy them?
yes i had some bosch super 4'z in my st162, i say "had" because my car is now "deceased" but they only made the slightest difference at low revs, in higher revs it was not noticable, plus they needed cleaning bout 4 times a year. but i believe it was a worthwhile investment for the small cost,
I used them ages ago in my Soarer after my friend used them in an R33 GTS-t. He said they made a big difference on his, but i thought they were actually worse on mine. Gone back to NGK's now.
