Review on NGK 1402 Spark Plug by Tim Beardsley

My friend bought the 07 RDX about 3 years ago and complained about rough idling. I advised him to change the spark plugs and air filter. The two most common culprits. Well, with my big mouth, I finally made a replacement for it. SPECIAL FOR THE 2007 ACURA RDX, these plugs fit perfectly and according to my friend the rough idle stopped immediately, a very noticeable difference. a way. I also recommend replacing the air filter, so that's an even bigger improvement. AND THE LAST. I HAVE VIEWED THE SELLER'S PHOTOS. THIS IS NOT A PICTURE OF THE SPARK PLUGS YOU WILL RECEIVE. 1402 IS MUCH LONGER AND HAS A VERY EXCELLENT LONG THREAD, MORE THAN AN INCH IF NOT MORE.
