Todd recommends the W3DPO's for all the power levels for the 3.2 Carrera. They are the best, and fire reliably with the OEM ignition. He also recommends the W3CS plugs, but they might be a bit harder to fire with the stock ignition @ higher power levels, so you'd need an aftermarket CDI to fire those reliably when you step up to the big power systems.

One thing is certain, the stock Carrera plugs are too hot for the boosted configuration.

I'm running W4CS in my motor and they seem fine I'll probably step down a notch to the W3CS when I change plugs next, as they are in the right heat range.
