5 Stars but read all of the review please
Read all of this please: I give them 5 stars because of cost and performance. They were much more expensive in my local big name auto parts store (50% more). My 2015 Honda Fit had 72,000 miles on it. Honda says replace the plugs at 103,000 miles or seven years, which ever came first. I had original plugs in it and exceeded the seven year mark, but was 30,000 short of the mileage mark. I noticed my idle was just not quite as smooth as it could be. I replaced the original plugs with these and WOW! there was a very noticeable difference. WHAT YOU SHOULD KNOW: For my Fit these are the "correct" plugs per NGK. However, and this is the big one: they are NOT the OEM original plugs Honda installs. These are the "IX" version not the Laser version. The difference is in the side electrode design. The Laser model (which has a slightly different number) has a longer lasting side electrode and are rated for over 100,000 miles. This model does not have that better side electrode and is rated for (depending on source) 30,000 to 50,000 miles. From experience I would say under normal driving 40k to 50k is a reasonable expectation. Our Fit is a run around town car and only goes about 6,000 miles a year, or even less. This version of the plug will last us like seven more years, likely longer than we will keep the car. This version was just shy of $30 for a set of four compared to OEM plugs which would be something like $100 to over $160 (at a Honda dealer). They work super well. The difference in performance was immediately noticed, the car runs really great. The gas mileage seems maybe slightly better, too soon to tell. I could not be happier with them and their price. Note, the one's I got were made in Japan. They do take a 14mm spark plug socket if you don't have one there are lots of choices here on Amazon. I got the one with a flexible drive end but no built in extension. ( I have plenty of those in different lengths so I could use exactly the one that worked best). I would recommend these to anyone as long as they understand just what they are buying and how long they will last compared to the OEM part number.

that this was a structural material failure
defective and failed immediately after installation. Right after installing them, the engine started shaking violently and misfiring under heavy acceleration. When I removed the spark plugs to inspect them, I discovered that the ceramic insulators were completely cracked and broken. The spark plugs were installed carefully using the correct tools, so this is clearly a structural defect in the ceramic material. It was a very dangerous situation as the broken ceramic could have caused catastrophic engine damage. I have already replaced them with a different set, and the vehicle is running perfectly now.
