"Very good plugs, increased performance and gas mileage.
Installed in my fit and Titan." —Donald S from Muskegon, MI bought a Pulstar Performance Series Spark Plugs for a 2005 Nissan Titan, 5.6L V8.
"Not sure if there is a difference in HP/Torque since I havent been paying attention to my MPG readings and such but you can definitely feel a little more pull when you hit the gas. As for gas mileage, it probably did increase but i'm not sure by how much. Not sure if they were worth 100 bucks but i needed new spark plugs anyways and this seemed like a good bet." —Elizabeth B from Lakeside, CA bought a Pulstar Performance Series Spark Plugs for a 2005 Nissan Titan, 5.6L V8.
"Low to moderate power increase at low idol. Have not noticed any mpg increase but then again Titans are not known for being economical and especially with gas prices as high as they are for 91 octane. Overall decent pick up. Too soon to say whether or not they were worth the $100. Time will tell." —Henry G from Yuma, AZ bought a Pulstar Performance Series Spark Plugs for a 2005 Nissan Titan.
