No troubles. Review: It seems genuine NGK product. Performed comporably to the original part that it replaced. - I bought this spark plug for 2019 Mazda CX5. I read several negative reviews that made me concerned. One reviewer indicated that the spark plug gaps were incorrect. I checked mine and all four were correct. Note that the spark plug for turbo version of Mazda's Skyactiv engine has a differerent gap than the non-turbo engine. I am wondering if some of the reviewers are misapplying the part. There was also a complaint about loss of fuel efficiency after replacing the spark plugs. That is serious becuse the engine is a direct-fuel-injection type and it is prone to carbon buildup if fuel is not fully combusted. I decided to collect my car's baseline mpg data before I replace the spark plugs and compare it to the mpg I will be getting after replacing the spark plugs. It turns out many things affect the mpg. I had to collect average mpg over a minimum of 40 mile trip to get a repeatable and reliable data. Ambient temperature and vehicle speed (mph) also affect the mpg. I collected mpg data on long trips from Dallas to Houston, Texas. The 1st was on Dec 24, which was before replacing the spark plugs. I started with a full gas tank; drove at posted speed limits for 261 miles; and when I arrived in Houston, it took 7.582 gallons of gasoline to fill the tank back to full. That resulted in 34 mpg. I replaced the spark plugs on Dec 31st and made another trip from Dallas to Houston on Jan 7th. This time, the trip consumed 8.497 gallons for a 262 miles trip which resulted in 31.5 mpg. That was a loss of 2.5 mpg with the new plugs. I knew that the ambient temperature was lower for the latest trip compared to my trip in December. I decided to repeat the test again. Today, Feb 4th, I made another trip from Dallas Houston. The ambient temperature was 61deg F when I left Dallas and it had dropped as low as 53 deg F at some point in the trip. It was back to 61 deg F when I arrived in Houston. This time, the trip consumed only 6.786 gallons to travel 265.3 miles; which equals to 39.1 mpg! I am wondering if temperature alone can explain the increased mpg for the latest trip or somewhat the spark plug needed some time to be broken-in before it performed well. I do not know the answer. My conclusion is that my new spark plugs are performing as well or beter than the old spark plugs. Will I buy these spark plugs from desertcart again? Probably not. Yes, the part performed well, but I still don't want take a risk of buying a counterfeit which could damage the engine, just to save something like $20 or $30. Next time, I will buy only from a Mazda dealership or from NGK authorized distributor. AutoZone, Advance Autoparts, O'Riley and NAPA are all authorized NGK spark plugs distributors. ## Features - Fit type: Vehicle Specific - Laser welded Iridium center electrode tip ensures high durability and greater spark - Platinum disc welded to backside of ground electrode provides long life - Longer insulator nose prevents fouling, Corrugated ribs on insulator prevents flashover, and the triple gasket seal eliminates combustion gas leakage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00P179CW4 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #243,284 in Automotive ( See Top 100 in Automotive ) #1,399 in Automotive Replacement Spark Plugs | | Brand | NGK | | Brand Name | NGK | | Compatible with Vehicle Type | Car, Truck | | Core Material | Iridium | | Customer Reviews | 4.6 out of 5 stars 244 Reviews | | Gap Size | 0.04 inches | | Global Trade Identification Number | 00087295941249 | | Included Components | SPARK PL | | Item Type Name | Accessories | | Item Weight | 0.04 kg | | Manufacturer | NGK | | Manufacturer Part Number | ILKAR7L11 | | Manufacturer Warranty Description | Limited Warranty | | Model Number | 94124 | | Number of Items | 1 | | Number of Packs | 1 | | OEM Equivalent Part Number | PE5R-18-110 | | Thread Size | RM | | Top Material Type | Metal | | UPC | 087295941249 | | Unit Count | 1 Count | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** NGK - **Core Material:** Iridium - **Thread Size:** RM - **Top Material Type:** Metal - **Vehicle Service Type:** Car, Truck ## Images ![NGK (94124) ILKAR7L11 Laser Iridium Spark Plug (1 Plug) | Replaces PE5R18110 B2401-HA00F PE5R-18-110 4711 IXEH20TT 9683. 80k-100k mileage rated. - Image 1](https://m.media-amazon.com/images/I/815lHy7vB4L.jpg) ## Questions & Answers **Q: This work for a mazda 3, 2012 skyacti. 2.0???** A: Yes, this is what I used when I changed my spark plugs on the Mazda 3, 2012 Skyactiv 2.0. **Q: This what confuses me. According to the manual a Mazda 3 2012 skyactiv 2.0 requires spark plugs gaped at 0.03-0.033; these are gapped at 0.044???** A: this is an updated plug from the original owners manual. The plug comes with an updated gap (.0414 to .0452) due to the technology of the plug. **Q: What size spark plug socket for ILKAR711 plugs? I’ve seen 9/16, 14mm and 5/16** A: 14 mm works the best. The others are not long enough to cover the whole spark plug. I got my 14 mm socket at O’reilly auto parts but you will need an extension. **Q: I have a 2014 Mazda 3 S touring 2.5L, my spark plugs are part# pe5r18110, how do these plugs compare? whats the difference between the 2?** A: NGK iridium is the OEM part. The only difference is one is labeled Mazda and one is labeled NGK ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product *by S***S on August 31, 2025* Installed myself (Youtube University, no experience) and been seen by a dealer.
