"Since I recieved the spark plugs, it has been a rocky road. Once I installed them, one of the plugs caused one of the cylinders to misfire. As a result, the SES light came on. I replaced the plug with the stock one for the time being and spoke with Pulstar. Ever since, the SES light went on once for below threshold exhaust on the Cat sensor. These are the results so far: improved MPG, yes nearly 2 MPG better; more power when carrying a payload; and easier starting." —Edgard D from West Hills, CA bought a Pulstar Performance Series Spark Plugs for a 2009 Nissan Frontier, 4.0L V6.
