Review: Excelente producto mi camioneta funciona muy bien
Review: 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.

## Questions & Answers

**Q: Has anyone upgrade from platinum to iridium for a Yamaha F225 4 stroke outboard engine? If you have, I'd like to hear comments regarding the change.**
A: I ‘ve been running the iridium plugs in my 2008 Yamaha F225-TXR for three years as I use my bout around 400-500 hours a year, and did not want to have to change plugs every 100hr. I have ran them as many as 250 hr between spark plug changes. If you buy on line you have to make sure they are genuine NGK Spark Plug, cause I bought 1-set of Plug where the boxes looked just like the Official NGK Plug box but they were not!  When I changed them out the electrodes were gone. I noticed a big difference when I switched to Iridium plugs the motor runs so smooth that at idle you can’t hear the motor running. You can call NGK and they will cross reference the factory plug to there Iridium plug for your application.

**Q: does this item fits nissan teana 2003 and nissan xtrail 2001?**
A: In some regions of the world, the Nissan Teana is also referred to as the Nissan Maxima and in relation to your question my mechanic has advised that YES, these plugs would also fit both the Teana and xtrail.  They are also referred to as long-range plugs.

**Q: would these fit a ram rebel 2018?? i need 16 don't you sell individually?**
A: NGK 4469 will fit 2018 RAM 1500 5.7L V8. Please use this link for set of 8 (you will need to get 2 sets for 16 plugs)

### ⭐⭐⭐⭐⭐ Review
*by J***N on 15 January 2026*

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.
