Just a warning - I just bought the PFR6H10 plugs to resolve a hesitation around 2700-2800 rpm in my '93 9k CSE (200hp), which they did - but at a noticeable loss of low end torque, and I think a reduction in peak boost. However, the power is very smooth. I've not yet put my calibrated boost gauge on it, but I will in the next day or two and I'll post the results. I'll also compare the boost against the stock BCPR7ES-11 plugs. One other thing - after putting in the PFR plugs, resetting the ECU by disconnecting the battery, and making several adaptation runs, I'm getting a check engine light after the car has been idling for an extended period (10 minutes...charging the old 900's battery). The flash code indicates an 02 sensor problem, which I know I don't have.
