2009 Nissan Xterra GCC. Just installed them on 08-10-2023
I noticed a slight vibration on idle, which became pronounced when I turned on the AC. There was an oil leak on the plugs due to the seal on the valve cover going bad. I had to change the valve covers (Left, right), and plug these in; the car runs smooth. Will update in a couple of months if there's any change in the performance.

I installed this 6 pack of NGK Iridium IX LFR5AIX-11 plugs in my 2013 Xterra a few years ago and they have been working great ever since. The truck starts quickly, idles smoother, and the throttle response feels more consistent than it did with the worn factory plugs. The plugs arrived well packaged and all looked clean and correctly made. I still checked the gap on each one before install and torqued them to spec. Since then I have had no misfires, no check engine lights, and no weird cold start issues. For the price, the durability has been the best part. I do a mix of city driving and highway trips and they have held up without any drama. If your vehicle calls for this exact plug, I would buy them again. Just make sure you confirm fitment for your engine before ordering.
