I just changed the spark plugs and wires my corvette 02 and I have made Bosch Platinum spark plugs 4. The corvette is going badly, I can not speed up, shakes and gives many shocks, it seems that something is going to break. I removed the Bosch, I relocated the former, a Denso Iridium IT20 and works fantastically. The second time I returned to remove the Iridium and I reinstalled the Bosch, to make sure that the last time she had already spent properly installed .... same thing again, shaking and very big vibration. between this and the intensity of the headlights I'm going crazy. Help please.

Thank you!

Don't use the Bosch Plus 4. It's not a very good plug for a C5. The Denso IT-20 is an outstanding plug for the LS1 in a C5. In fact, I use Denso IT-20s or IT-22s in my C4's LT5, in my C5's LS6 and in my C6's LS7.

They are a great product.

I'm sorry but I don't know about the NGK 7164.

I only use Denso IT-20 or IT-22.

The NGK's should work. I don't use any of the multiple conductor spark plugs.
