The OEM coils on my stock 2001 XKR are becoming marginal where as they misfire if the spark plug gap exceeds 0.035 inches.
Ford Mustang users claim performance and overall increases across the power band with aftermarket coils.
Does anyone have any first hand experience using the Holley/Accel 420005 ignition coils on the 2001 vintage XKRs ? - or know of aftermarket coil alternatives?
Thank you,
