Box Contains 1 x iridium spark plug Review: いい感じ(๑•̀ㅂ•́)و✧ - デミオDYに乗ってます。交換は車イジりが多少出来る人はそんなに苦労しません。10万キロ過ぎたあたりで交換しました。調子は良いです。出来る人は交換するべきです。 Review: OEM REPLACEMENT GIVES PLEASANT SURPRISE! - AFTER RECENT CHECKS OF THE SPARK PLUGS IN MY 2007 PRIUS TOURING MODEL, I KNEW IT WAS TIME FOR REPLACEMENTS. I WAS TEMPTED TO TRY THE NEW PULSE TYPE PLUG, BUT DECIDED TO OPT FOR A MORE CONVENTIONAL OEM TYPE PLUG. A BRIEF INTERNET SEARCH RESULTED IN NUMEROUS IRIDIUM TIPPED PLUGS, BUT THE DENSO 5303 IRIDIUM PLUG HAD ONE OF THE SMALLEST CENTER ELECTRODES AT .004. WHAT THE CLAIM IS THAT THIS SMALL SIZE ELECTRODE WILL FIRE QUICKER. WELL, THAT WAS GOING TO BE PUT TO THE TEST. ROUND ONE WAS A HIGHWAY CRUISE FROM MY HOME AT PORT ANGELES,WA. TO SEATTLE WA., ABOUT 125 MILES AND I AVERAGED 50.3MPG, BY ONBOARD COMPUTER. NEXT WEEK,AROUND TOWN DRIVING TURNED IN CONSISTENT 40+ MPG, WHICH WAS AN IMPROVEMENT OF OVER 5MPG. ALL THIS HAS LEAD ME TO RATE THIS PLUG AS EXCELLENT AND AN EXCELLENT CHOICE FOR OEM REPLACEMENT FOR THE PRIUS. I ALSO FEEL THAT FOR CONSISTENT HIGH MILEAGE IT MAY BE NECESSARY TO CHANGE PLUGS EVERY 25,000 MILES OR SO. YOU SHOULD CHANGE IF YOU HAVE NOTICED YOUR MILEAGE DROP RECENTLY. AND SO FAR THE DENSO 5303 IRIDIUM PLUG HAS BEEN A SOLID PERFORMER! ## Features - 13^0042511053038 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CJ048W | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | 751,323 in Automotive ( See Top 100 in Automotive ) 2,715 in Car Spark Plugs | | Brand | Denso | | Brand Name | Denso | | Compatible with Vehicle Type | Car | | Core Material | Iridium | | Core material | Iridium | | Customer Reviews | 4.3 out of 5 stars 215 Reviews | | Gap Size | 0.4 Millimeters | | Global Trade Identification Number | 00042511053038 | | Item Weight | 0.05 Kilograms | | Manufacturer | DENSO Europe B.V. | | Manufacturer Part Number | IK16 | | Model Number | IK16 | | OEM Equivalent Part Number | 101000044AA, 1UD318110, 224012J204, 55182623, 8971702680 | | Thread Size | 14mm | | Thread size | 14mm | | Top Material Type | Iridium | | Top material type | Iridium | | UPC | 042511053038 | | Unit Count | 1 count | | Vehicle service type | Car | ## Product Details - **Brand:** Denso - **Core material:** Iridium - **Thread size:** 14mm - **Top material type:** Iridium - **Vehicle service type:** Car ## Images ![Denso IK16 Iridium Spark Plug - Image 1](https://m.media-amazon.com/images/I/711pxap3NNL.jpg) ![Denso IK16 Iridium Spark Plug - Image 2](https://m.media-amazon.com/images/I/61HcqYIEECL.jpg) ![Denso IK16 Iridium Spark Plug - Image 3](https://m.media-amazon.com/images/I/71cwybyiGpL.jpg) ![Denso IK16 Iridium Spark Plug - Image 4](https://m.media-amazon.com/images/I/61wmuPrw5LL.jpg) ![Denso IK16 Iridium Spark Plug - Image 5](https://m.media-amazon.com/images/I/61e9kl7pPpL.jpg) ## Questions & Answers **Q: Hi, this package how many sparkplug contain, one or four?** A: They are packaged 1 spark plug per box, for about $8. Some retaler sell 4 packs and six packs. Again, priced at approximately $8 each.Iridium plugs are the best. I pulled 4 out of a 2004 Camry with 107,000 miles. They looked like new. On the Camry the spark plug swap takes about 3 minutes per plug, but some vehicles are much more challenging. On those you should pay extra for the best plugs so you don't need to pay to have them replaced every year. **Q: does it fit 2010 vw passat 2.0 tsi, dsg? what is the differecence to denso 5304?** A: I've just check Denso's website and it should fit all 2010 VW Passat 2.0.The 5304 is the next cooler version of the 5303.If you drive harder than average, live in southern state, and/or use your vehicle all day, then consider the 5304. **Q: Is it normal these plugs lasts 20k miles? ground electrode wore out** A: I dont think so. My original plugs lasted 65,000 plus miles **Q: Does it fit 2005 Corolla 1.6 cc vvti 4 cylinders ?** A: I assume you mean a 1.8 cc vvti 4 cylinder which takes Denso (3324) SK16R11 Iridium Spark Plug, Pack of 1 https://www.amazon.com/Denso-SK16R11-Iridium-Spark-Plug/dp/B0012Q9ZSO/ref=au_as_r?_encoding=UTF8&Make=Toyota%7C76&Model=Corolla%7C1013&Year=2005%7C2005&ie=UTF8&n=15684181&newVehicle=1&s=automotive&vehicleId=1&vehicleType=automotive ## Customer Reviews ### ⭐⭐⭐⭐⭐ いい感じ(๑•̀ㅂ•́)و✧ *by 新***ん on 6 June 2022* デミオDYに乗ってます。交換は車イジりが多少出来る人はそんなに苦労しません。10万キロ過ぎたあたりで交換しました。調子は良いです。出来る人は交換するべきです。 ### ⭐⭐⭐⭐⭐ OEM REPLACEMENT GIVES PLEASANT SURPRISE! *by B***S on 2 August 2009* AFTER RECENT CHECKS OF THE SPARK PLUGS IN MY 2007 PRIUS TOURING MODEL, I KNEW IT WAS TIME FOR REPLACEMENTS.
