UPDATE: On my test of the K Suspension Viper Coil pack kit.....
Several months after installing the kit I started receiving misfires on certain cylinders.
While removing the RIPP Supercharger spark plug wires several of the plug wires pulled free of the clip and I found the boots had split causing an arcing to ground. The spark plug clips holding the plug wire to the spark plug were not crimped properly and the split was at a production seam.
Before anyone asks IF I pulled on the plug wire during removal; NO.... I grabbed towards the middle of the boot and wiggled side to side.
I removed the entire kit and reinstalled the factory ignition rail.
Contacted K Suspension early last year and they referred me to the spark plug wire manufacturer.
I have been in touch with the manufacturer several times over the past year by email and phone; I was informed the plug wires are on BACK ORDER due to a lack of materials.
After a year being on " PERMANENT" back order; I am not holding my breath that I will ever receive the replacement plug wires.
The purchase of the kit started out as a test to see if there were any actual or perceived performance gains; there were none.....
I had no intentions of keeping the kit installed so I would say that the problems with the plug wires make this test a failure.
