NGK 94124 ILKAR7L11 Laser Iridium Spark Plug, Pack of 4

Best quality. Same like OEM.Spark plug quality:Best

First update on mileage achievement with new NGK plugs-Aug2024- Finally took the car on a long distance drive of 406 miles one way. The almost 'all highway' mileage that I achieved with these new plugs was 38 miles per gallon with cruise control on at an average speed of 65mph. If I went the speed limit, of 70MPH, I would at least expect about 35 Miles Per Gallon.So after the installation of these new spark plugs (and cleaning the mass flow induction sensor (very easy to do via you tube video)) my mileage has rebounded by about 7 to 9mpg. That is an incredible mileage refresh for my 186,700 mile engine.Let this be said. NO, spark plug is going to make your car perform better than it was design to. But I recently noticed the mileage on my 2015 Mazda 6 manual had deteriorated. Whether highway or street driving, it never used to fall under 31 mpg. After recently seeing results of 27 to 29mpg, I realized the last time I had changed the plugs was about 68,000 ago. Mazda recommends 70,000 between changes.I replaced the Mazda factory plugs with the NGK Iridium's as purchased here. Although my tank was not really full to get a good accurate measurement at the time. When I did fill up my tank, I noticed the mileage had improved to 32mpg overall. When I measure it again, I should get around 34 to 36mpg, which is normal in my previous history with this vehicle.There are videos on you tube that clearly show you how to replace plugs for this Mazda 6 of the generation that I had. So give it a try.Oh, don't make the mistake I did. Since I'd replaced the plugs before, I assumed I still knew where my 8mm socket (to remove the coils) and my 9/16 spark plug socket were. I was wrong! A job that should have taken less than 45 minutes, took more than two hours because I have to purchase those items from Autozone. Geez.Photo is of my Mazda plugs that installed about 68,000 miles ago, versus the new NGK plugs that I installed a few weeks ago. No, I did NOT check the gap width on the new plugs, I just installed them. Youtube videos will show you how to do that too.

Exact replacement for my cx5. Gaps were spot on. Just like OEM (because they are)! Good price and quick delivery sealed the deal.

Works as it should

Outstanding quality. Got a set for my 2017 Mazda and they were gapped correctly, all had the same ohms reading and all worked perfectly. I recommend them to everyone wanting OEM spark plugs, you will be happy with the quality.

Though Mazda factory installed Denso Spark Plug in 2013 Mazda3, this NGK ILKAR7L11 is EXCAT match to factory installed spark plugs. I just recently replaced my spark plugs for my 2013 MAZDA3 at 100K miles, using this NGK spark plugs, and it worked 100% perfect, !! NO ISSUE!!I would advice any 2013 Mazda3 owner to order this plug on Amazon because it's the BEST VALUE compared to any OTHER competitors.You will need 9/16" magnetic spark plug socket, extended 10mm socket and Di Electric Grease. And preferably torque wrench (though it's not necessary for professional but for normal Joe DIY project I would recommend to get torque wrench).Roughly $45 for spark plugs + $8 for dia electric grease + $30 to $40 torque wrench + 10mm deep socket, you are looking at roughly $100 total project cost for spark plugs replacement of your 2013 Mazda3YOU WILL SAVE AT LEAST SOMEWHERE FROM $125 TO $150 IF YOU BRING YOUR VEHICLE TO ANY SHOP OR DEALER TO REPLACE YOUR SPARK PLUGS.On top of your saving you can reuse your investment of torque wrench, dia electric grease and 10mm deep socket unlimited times for your future projects.

Great fit for my 2012 Mazda 3Package came fine but box inside was smashed up bad. Basically wasn’t the delivery driver but whoever fulfilled the order used this beat up box of spark plugs. Thankfully they were okay and 3 of the 4 were perfectly pre gapped. The last one was slightly off. Works great.

very good
