    • OEM Quality. Smooth Idle and Easy Install
Fit perfectly and came pre-gapped correctly for my application, which made installation easy. I’ve always heard NGK is the go-to brand for these cars and now I see why. Solid quality and no issues at all so far.

    • Reliable long-life plugs for my 2013 Xterra
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. ... show more

    • NGK 4469 plug-2015 Nissan Desert Runner
Review Image by SuperDave
Just got around to installing these plugs and they worked like a champ. Plugs in the 4pack did scan as true NGK plugs not knockoffs. The other 2 loose ones were identical. They do appear to come pre-gapped at .042, so I had to open them up a hair to .044 for my 2015 v6 4.0 desert runner. Great value & I Would not hesitate to buy again. *EDIT* For those interested I didn’t know this until I replaced my plugs, but the original plugs were Iridium LASERS. They lasted 150,00 miles, but i see they cost about 3-4x as much. I attached a pic of the originals. NGK makes great plugs and im sure both work fine. Just sharing the information for my fellow DIY’ers! ... show more

First I would like to thank the seller for selling real NGK Iridium spark plugs. Thank you. I just bought a set from ebay that were fakes and these are legit! The real ones metal and threads look like stainless steel while the fakes look blue! There are several ways to tell the difference but that is plain and clear. I would not hesitate buying these plugs. ... show more
