A friend is telling me Iridium Denso 4 platinum spark plugs are better than
Bosch Platinum 4 plugs. 300Zx drivers and mechanics, what do you think ?

I'm using Bosch 4 plugs and saw a small improvement in performance, better
engine response and gas mileage over the Nissan dealer plugs the previous
owner paid for.
I cleaned the throttle plate too, probably the first time since a human
has touched it since it left Japan.

I don't know much about Iridium plags but Bosch ha been around a long time
and is used by many German car co.s
and many of the parts store chains stock Bosch now.
Everybody weigh in with your opinion and or experience.
No flip flop, please.

Use the factory plugs.

BS, that's in your mind. It;s like people who claim split fires do this,
ain't going to happen.

And NONE use the "retail platinum" versions in any of their cars.

You will not find a better plug for the 300ZX than the stock NGK plugs.

Anything is better than Bosch for spark plugs. If you have ever
experienced a no start condition when you have a year on the plugs you
can rest assured that the plugs are Bosch. I had them in my Corvette
and that is what they did. I had them in the kids gokart and the same
thing. In the lawn mower the same thing. And, just last weekend I
changed the plugs on a friends Blazer and the plugs were Bosch. They
looked new. But, when you would try to start the car in the morning it
took several attempts to get the car to start. You got me as to why
this condition exists. But, that has been my experience. So, for me it
is anything but Bosch. Maybe if you have a Porsche or a BMW? But, I am
done with Bosch plugs.

And even they won't touch those "platinums", they have special plugs made
by bosch for their cars.
