i installed these on my 16 Sportsman 1000. even after having the pcm flashed for better performance, it still had this lag/bog type issue when cracking the throttle... almost like a delay in throttle response. these plugs made it perfect. a noticeable improvement in throttle response and very reactive with off idle and mid-range throttle activation. the factory plugs just aren't correct for that machine (comes with autolites) machine rips even with 30" tires and all stock clutching. perfect compliment with the tune I had done.

None of them came gapped properly! They were supposed to be .04" but they were .035"Took me long time to gap them again.

Using in my Polaris 850 xp eps. Seems to run about the same as before, only have a few hours on these plugs so far so we'll see how the longevity is. Price is the reason for 4 star.

They do fit my 2015 Polaris sportsman 1000. Never assume gap is correct for your usage. These were not set to Polaris specification. Now will I buy these again? Yes. I noticed a midrange response difference. Not something braggable just took the stuffiness out. If that makes sense.

Spark plugs haven't been changed for 100k miles so this is the first spark plug change I've done for my S63. These are the exact same part number and ngk markings as the mercedes stamped original factory spark plugs, even the mercedes stamped ngk plug says made in Japan just like this one. They just charge you extra for them stamping the mercedes star symbol on the plug.Immediately I felt throttle response and power increase. My mpg also went up. But these were all expected since the manufacturer interval chnage is 60k for these iridium spark plugs. Rest assured every one of the markings are identical to the orginal mercedes ones.So if you are near or past the 60k interval definitely suggest buying these to change your spark plugs, many benefits to be had. Don't be skeptical just because it doesn't say original, because NGK is one of the top names for spark plugs, that's why mercedes and bmw use them and restamp their logo on them to put in their cars from factory.This was my first time experiencing iridium plugs, my last car an E46 M3 required platinum plugs, I read iridium is a version of platinum and both offer longevity as a selling point. This was the cheapest place I found them vs ebay and pelicanparts. Anyways good luck in your buying decision.

Installed these without a torque gauge or anti seize... But... When I put the coils back in place on my e63 amg, I immediately went from rough idle to smooth, huge boost in torque at 5,000 rpm and fuel econ went from 21 mpg to 26.5. Given its at 94,000 miles and first tune up... And no other plugs to compare to, these are working great. Arrived pre gapped at .044 (I am hoping lol!)UPDATE: Fuel mileage reached 28.2 mpg in a e63 amg. All I did was change the spark plugs to these laser iridium, and add a little heat shield under the air filter housing. !!!!!!!!!!!!! Now I am shredding tires in automatic, switching from 2nd to third!
