ACCEL 140017 Direct Ignition Coil

Some years back, I had replaced the wires and plugs with new stock/OE components on my 1999 Cadillac Deville (Northstar 4.6) and one coil went bad about a thousand miles later. Rather than replace the one (serving two cylinders) and the price for these about the same as OE, replaced all 4 coils with the Accel coils. Very pleasantly surprised by the difference in performance! Tip-in throttle response was quicker/sharper and it seemingly had 'less effort' in general driving, especially in passing and/or accelerating at any speed, under normal of heavier throttle situations. An all-stock car and just this 'upgrade' was a night & day difference. Also pretty funny to open the hood to a stock engine along with the plastic engine cover, but the bright yellow coils sticking out like a sore thumb along the firewall! A couple of of Jiffy Lube mechanics had some things to say! Ha! I can only imagine what they would be like in a 'real performance' car, like a Corvette or Camaro.
