NGK LKAR6AIX 11 Spark 91187 Iridium Review

These are great spark plugs and quality parts but they are not properly spaced for Sentra 07-12. When these are installed, the engine will vibrate a little when idling. While they match the engine, they are not perfect.

Someone reported that they are Chinese fakes. Mine are listed on the box and stamped on each spark plug, Japan. I always use NGK/NTK products as they are quality components. I used these spark plugs on a 2006 Nissan Frontier XE with a 2.5 liter engine. These plugs are the smallest diameter I've seen, they're 14mm.

NGK spark plugs rear engine. Acceleration. Although the manufacturer states a longer service life of 100,000 km. In my case for prevention Good wear resistance (changes every 80,000 km). I recommend 100%, good price Will buy again.

Suitable for Nissan versa 2014 MY. The high gas mileage of this car has been restored. I've driven it 62,000 miles and noticed that the gas mileage isn't as good as it used to be. Since I change the air filter every 3000 miles I knew the air filter wasn't the problem so I figured it was time for the first reverse adjustment. And whale! Now runs smooth as silk. I will never buy standard candles again.

I just installed these on my 2014 Nissan Versa and they fit like a glove. The old ones were pretty bad, but these gave the engine new life. I will give a more detailed review after 1 month of use to let you know how it works. First, they were all pre-calibrated at 0.39 inches, and for the 2014 Versa they should be at 0.44 inches. I just set the spacing to how it should be and you're done. Would buy again!

They are perfect for 2012 Nissan Versa 1.8. The gap should be 0.044 and it takes a few minutes for them to form a gap. You need a 14mm spark plug and not just a deep head to remove and replace. Also, you'll probably want to get an intake manifold. Pad while you're at it, since you're going to take it off anyway. Good traffic and the car runs smoother and increases mileage.

NGK has always made excellent, high quality and durable products. When I bought these spark plugs at a discounted price of $5-$10 (depending on where you buy them) I felt damn good. Concluded that when inspecting when applying a lubricant to the threads prior to installation, I noticed micro-cracks on the porcelain part of the connector; on opposite sides. Glad I caught it before I installed it in my girlfriend's car. I ended up having to buy ONE spark plug which cost over 1/4 the price I…
