Spark Plugs

[Racer 007]

I have read numerous things regarding how much Bosch spark plugs suck and that we should just stick to the NGK Platinums.

How many people have had problems with the Bosch's or any others for that matter?

Would my hesitation problem likely be a side effect of these plugs?

I had Bosch Platinums in my 93 and changed them to NGK's and it made a nice improvement.

Man I've heard it all to many times also with the bosch's. In fact when I was about to do my plug change I bought some of those then read that they suck and never even put them in ended just buying the NGK's. You don't have to get the NGK's though I think it is just the bosch's in general that suck.

I've had Bosch platinum plus 4 in my '91 Stealth RT DOHC for the last 2.5 years and 30K+ miles; the engine runs like new with 155k miles on the clock. The original NGK's I had problems with miss firing under acceleration when the engine was cold. Now it doesn't take much for the Bosch's to light up the cylinders even in the cold midwest winters!!

I get my plugs and wires today. I got stock plugs and NGK's because all I hear about them is great things for a nearly stock car. Now I hear that when you start to use nitrous, copper plugs are better.

I have heard that copper plugs are better no matter what. Platinum lasts a little longer but for what you pay on NGK plats vs. NGK coppers, the coppers are the way to go.

I had bosch platinums in my N/A before. They lasted all of 15k miles. I switched to NGK platinums and they work great. For nitrous use you will not want to use a platinum spark plug. Most (if not all) nitrous system manufactures tell you not to use platinum plugs when using nitrous due to the possibility of intake manifold backfires. I use a NGK racing Paladium plug and they work great. Of course they run about $17 each :).
