It fit my 2013 skyactiv Mazda 3. It gave me better gas mileage and seemingly, more power. Great product! Will be buying again.

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.

They work excellent and rather pay this $30 here than $12 or $15 each one at any autoshop nearby.

Apparently there are 2 different size spark plugs for the 2007 Toyota Camry. These are the longer, thinner thread. My engine uses a shorter thread and larger in diameter. You will want to pull a spark plug from your vehicle before ordering.

Lesson for the car maintenance hobbyist, make sure you have the right socket tool for these spark plugs, they are narrower than standard. Once installed they worked like a charm, no adjustments needed and performed without issue over normal driving.

I purchase NGK plugs for all my Asian vehicles, and these were for my 2014 Prius V. No problems with installation, fired right up, and runs like a champ, getting fuel economy exceeding CAFE standards. They're pricey, but they are what the car requires, and if you're lucky, you'll only do these about three times in the car's useful life with a service interval of 120K miles.

I bought these for my 2014 Mazda Cx5 Gs. I've had the car for 7 years and have never changed the spark plugs. I was getting a few lights on the dash including the engine light and a bit of stuttering when starting the car. I decided to change the spark plugs as I've almost put 90,000kms on the car since I've had it.Very easy to change out and came as a 4 pack. Price was very reasonable and very good quality. I had them changed out in under 15minutes. The car started up instantly. After removing the old spark plugs they were swollen and burnt out. Glad I found these on Amazon at a reasonable price. It's only been 24 hours but so far so good and the car starts up and runs smooth. I will update this in a few months if any changes. I highly recommend these spark plugs and delivery was literally overnight!

Las puse en un Mazda 3 2015, con motor de 2.5L, las bujias que tenia no me estaban dando problemas pero ya por kilometraje decidi cambiarlas,el consumo que me mercaba la computadora era por cada 100kms/ 8.0L, despues del remplazo bajo a 100km/ 7.4L, las instale con el distribuidor me hicieron un comentario que tal vez a altas revoluciones sienta una diferencia pero hasta el momento no he tenido ningun problema y ya recorri 10,000 kms desde el cambio, quise hacer la review hasta que tuviera el primer servicio despues del cambio.
