  • 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
