The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine’s power is drawn out to its maximum potential. DENSO IRIDIUM TT spark plugs have a φ0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode. - The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions. - Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability. - All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00TPU9BWO | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #158,001 in Automotive (See Top 100 in Automotive) #1,091 in Automotive Performance Spark Plugs | | Brand Name | Denso | | Compatible With Vehicle Type | UTV | | Core Material | Iridium | | Customer Reviews | 4.7 4.7 out of 5 stars (225) 4.7 out of 5 stars | | Gap Size | 1 Millimeters | | Global Trade Identification Number | 00042511047051 | | Included Components | Spark Plug Iridium TT | | Item Type Name | Spark Plug | | Item Weight | 52 Grams | | Manufacturer | Denso | | Manufacturer Part Number | IKBH20TT | | Model Number | IKBH20TT | | Number Of Items | 1 | | Oem Equivalent Part Number | DENS7 | | Thread Size | 14mm | | Top Material Type | Iridium | | Unit Count | 1 Count | | Upc | 042511047051 | ## Product Details - **Brand:** Denso - **Core material:** Iridium - **Thread size:** 14mm - **Top material type:** Iridium - **Vehicle service type:** UTV ## Images ![Spark Plug Iridium TT - 4705 - Image 1](https://m.media-amazon.com/images/I/812UZ3IkwJL.jpg) ## Questions & Answers **Q: 2017 highlander v6 manual says i need (denso 3491) 0.031 gap, but amazon & rock auto says this denso 4705, 0.040 gap fits?** A: I can't honestly answer your question.
