    • Top Spark Plug Choice for My 2013 Nissan Sentra SV
I recently grabbed a 4-pack of NGK LKAR6AIX-11 Iridium IX Spark Plugs for my 2013 Nissan Sentra SV, and I'm absolutely stoked about it. These spark plugs slid right into my car like they were made for it, and ever since I put 'em in, my car's been running like a champ – not a single hiccup to report. My decision to change the plugs came from a recommendation by the mechanic at the car showroom. I didn't fancy forking out over $350 to the service center for what turned out to be a pretty straightforward job. But what's really ripper about this purchase is the price. Snagging a set of four branded spark plugs at such a fair dinkum rate is an absolute steal. I'm chuffed with this product, and it's given my car a real performance boost. I reckon anyone after a reliable and budget-friendly solution should give these spark plugs a burl. G'day! ... show more

    • Plug me in
I'm not mechanically inclined so, I took a small survey about what kind of spark plugs to purchase for my 2008 Nissan Altima...NGK brand got the best reviews. Apparently they come pre-gapped (whatever that means) and are guaranteed for a perfect fit for your vehicle. All that I know and what really matters is... my car starts up without issues. I'm a Amazon Prime member...of course, I had next-day delivery. Which made the process that much easier. ... show more

    • Good quality OEM replacement part.
I was skeptical but they were the exact replacement spark plugs for my daughters Nissan. Not the cheapest but comes with peace of mind with a good quality part.

    • Fixed the issue!
2011 Nissan Rogue was running rough and lost power. It would barely accelerate and vibrate , shaking badly almost thinking it was a transmission problem. Put 4 of these bad boys in along with a new coil pack and she running silky smooth. Just get them, half he cost than local.

    • 2012 Nissan Altima 2.5S Spark Plugs
These are awesome spark plugs. I used Autolite brand spark plugs and they were okay. I changed them after having them for 35k miles think they were causing my engine vibration. It turns out my aftermarket ignition coils were the culprit. I bought these because I wanted the OEM spark plugs since they were better after trying the Autolite spark plugs with the new OEM Hitachi ignition coils. The NGK gave better performance. I was happy to get them at this price. Usually they are more expensive. ... show more
