Major improvement in my 1997 B2300,
From an install perspective, not having to gap the plugs was a bonus. Essentially you open the box and install the plug. I highly recommend replacing the plug wires at the same time. I went with Bosch Plug Wires for max compatibility.
As far as performance, there is definitely good spark firing in all cylinders. The motor sounds great at low idle and at high RPMs. Make sure you have the right parts for your application and you will be equally pleased.

great plugs for 1999 toyota 4runner 3.4 motor,
I have also heard a lot of people complain about them including my mechanic, but they worked better than stock plugs in my vehicle. I will buy again.
