"I have had the plugs installed for two weeks now! Wow! What a difference in the performane of my 1998 Jeep Grand Cherokee Lorado. More hosepower and I can see a difference in the fuel consumption. I, also, put in Granatelli ignition wires (0 ohm resistance) and a new wells gold distributor cap and rotor.
The car performs like when it was new." —Gary L from Santa Barbara, CA bought a Pulstar Performance Series Spark Plugs for a 1998 Jeep Grand Cherokee, 5.2L V8.
