      i Actually has really bad generic spark plugs in my Acura 3.2CL. It was probably installed by previous owner. but once the change was made. I could actually feel the improvement in responsiveness. The car runs alot smoother on idle, and hopefully a combination of these things will produce a better gas mileage! Really high quality stuff. Btw, it is always good to check the gapping of these spark plugs before installing them. According to my gap gauge, These are not pre-gapped. Another thing to do is to stay away from those gap gauge coins. They can damage your precious metal.Be careful with these!I love them!!!

      I had a 1968 VW with the 1600 engine stock single port heads and single solex carb.It had that floating miss that the engine was known for. I did some research and decided to give these a try and at the time there were 12-13 dollars each I bit the bullet and bought some pre-gapped for my engine installed them and the engine started easier, ran smoother, and could take off faster. No more floating miss. I have since learned that due to my engine configuration it was harder for the stock style plugs to fire. I had also tried NGK V powers because I was trying to stay with a standard copper core for the air cooled engine. Bosch stock plugs just didn't work as well either.From my experience if you run high compression, aircooled, or hot engines use Denso Iridium plugs with the 0.4 wire.If you have a stock setup water cooled you might try halo plugs or sonic plugs to save money. I've had good results with those also. Iridium plugs 10-13 each or about 6 each for...

      I have used the Denso plugs on my cars & race bike. I don't notice much in the cars (other than I haven't replaced a plug yet) but on the race bike; which I would have to replace regularly; they have proven to last longer; and I have had less misfires at redline. Expensive; but worth it.(btw: asked someone to pick up a standard plug for my generator, they brought me an E3 plug -- avoid these; it cracked less than a month. Their arranty is "life of the engine" -- if it had completely fallen apart, engine life would have been over -- Avoid gadget plugs like E3, split electrodes, etc)
