    2015 Mazda 3 Hatchback 77,145 miles
    Installed yesterday on 2015 Mazda 3 Hatchback with 77,145 miles. I highly suggest using a magnetic socket. Relatively easy. A noticeable performance improvement. The old ones look pretty beat. I'm thinking replacing at 65,000 rather than the recommended 75,000 would have probably been better. Don't hesitate to do this yourself. I spent less than $50 on what would have been $180 at the dealer.

    5.0 out of 5 stars Perfect Fit and Excellent Quality
    Reviewed in the United States on June 25, 2023
    Verified Purchase
    The NGK LKAR7BIX-11S Iridium IX Spark Plugs are a perfect fit for my 2015 Lexus CT200h. These spark plugs provide outstanding performance and durability, making them an excellent choice for anyone in need of reliable ignition power for their vehicle.

    One notable feature of these spark plugs is their slightly slimmer design compared to regular spark plugs. This difference necessitates the use of a specific spark plug socket to ensure a proper and secure installation. It's important to have the correct tools on hand, but once you do, the installation process is straightforward and hassle-free.

    In terms of quality, the NGK LKAR7BIX-11S spark plugs exceed expectations. The Iridium IX construction ensures excellent ignition efficiency and longevity, allowing for consistent and reliable spark generation. This directly translates to improved engine performance and fuel efficiency. I have noticed smoother acceleration and enhanced overall engine responsiveness since installing these spark plugs.

    Additionally, I would like to commend the fast shipping provided by Amazon. It's always a delight to receive products promptly, especially when it comes to essential vehicle components. The combination of high-quality spark plugs and efficient delivery further emphasizes the convenience and satisfaction of choosing NGK LKAR7BIX-11S Iridium IX Spark Plugs for my Lexus CT200h.

    In conclusion, the NGK LKAR7BIX-11S Iridium IX Spark Plugs are a perfect fit for the 2015 Lexus CT200h. While their slightly slimmer design may require a specific spark plug socket for installation, the quality and performance they deliver are exceptional. With improved ignition power and enhanced engine performance, these spark plugs are a reliable choice. Combined with the fast shipping from Amazon, my experience with these spark plugs has been nothing short of impressive.

    Reviewed in the United States on April 2, 2024

    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.

    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.
