useless.. absolutely worthless.
I put some of these on the car thinking they would be somewhat better than the original ones, and BOY was i wrong (puts a whole new meaning to "learn from your mistakes"
Installation was fairly easy.. put new wires in along with them, took the car for a spin.. and what in the hell. The car stumbled horridly and i couldnt even spin tire on a DIRT road.. so we (me and my cousin) head back to the house to check for a loose wire / disconnected wire.. nothing.. pulled one of the plugs, and it was BLACK on the tip, pulled another one, the white part of it was CRACKED, pulled another one, cracked, pulled another one.. cracked. Pulled the last 2, and amazingly they were actually intact and fairly new looking.
Took them back to Auto Zone, and they wouldnt take them back.. so i said screw it and paid 30 bucks for a set of AC Delco rapid fires and stuck em in, WHAT a difference. tested out the performance and i laid about 8 feet of rubber.
Why are the platinum fusions so damn fragile? at 10 dollars a plug, you'd think they could handle a little V6, didnt tighten them very tight..
SO, 3 cracked spark plugs and a burnt one later, not to mention 100+ dollars later, my car is idling smoother, picking up alot better, and starting without hesitation.
-never- will i buy another item that says "Bosch" on it. And try not to flame me for getting Bosch, this was a learning experiance, and i learned the hard way.
Lesson Learned!
I'll take pictures of the Bosch plugs here in the very near future.
