They work. Gap was correct on arrival. They are functioning as intended for a 2014 Dodge Dart SXT 2.4l. They have absolutely no markings on them. Makes me question how the manufacturer knows which plugs are which if there are zero markings on them?

These spark plugs worked perfectly in my husband's car. The engine runs smoother, starts quickly, and we have had no problems at all since installing them. The quality is excellent, and they were easy to install. Great performance for the price. We are very happy with this purchase and would definitely buy them again!
Good quality.
Item as described. Fast shipping. Good price.
Good price, and fit perfectly for my 2015 Nissan Altima. The old ones had 104,000 miles on them.
These spark plugs fit my automobile and were a also a great price
Performance is very similar to the name brand spark plugs. It costs half the amount. My 2013 Corolla is running very smoothly after installation.
They are spark plugs, they work.

Good plugs may have to adjust the gap for your Rav4 they came slightly off but still recommend
Seems like they worked perfectly
They are great spark plugs that are correctly gapped. Toyota RAV4 now runs great.
