$15.49
Q:Would this plug work in my 2011 z71 chevy.    or should i go with the NGK IZTR5B11 ? Show Less
David G.
A:BEST ANSWERHi David, I'm glad to help you out. Yes, it would. And I highly recommend this Ruthenium HX Series since they are capable of providing up to twice the service life of the Laser Iridium and 4-times of service life of the standard nickel electrode spark plugs. I hope this helps, and if you're interested in this NGK spark plug, you can click on the link below for direct ordering to take advantage of our ongoing sale. Happy shopping. https://www.carparts.com/spark-plug/ngk/ng94567?can=CPAE1047 Show less
