Engineered with all-around laser welding and a built-in resistor, it ensures durability and electromagnetic noise reduction, making it an OEM-quality upgrade for cars and vans. ## Description The two needle-thin electrodes in DENSO’s patented Iridium TT design enable sparks to grow 360 degrees in all three dimensions, improving ignition performance and combustion output, increasing spark plug lifespan and reducing emissions. The lifetime of these plugs meet any OE engine maintenance requirement. Performance is higher due to the Twin tip technology and the Denso patented 0.4mm centre electrode ## Features - IXEH20TT | Twin Tip Plug | Tightneing Torque (Nm): 17 | 1 - Earthed Electrode | Diameter (mm): 12 | Thread Length (mm): 26.5 - The Finest Twin Tip plug with improved acceletation, fuel economy and longevity compared to single tip plugs. 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 | B06XSQ2C5M | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #108,339 in Automotive ( See Top 100 in Automotive ) #720 in Automotive Replacement Spark Plugs | | Brand Name | Denso | | Compatible with Vehicle Type | Car, Van | | Core Material | Platinum | | Customer Reviews | 4.5 4.5 out of 5 stars (60) | | Included Components | Iridium TT Spark Plug x4 | | Item Type Name | Spark Plug | | Manufacturer | DENSO Corporation | | Manufacturer Part Number | IXEH20TT | | Manufacturer Warranty Description | Includes manufacturer provided warranty | | Model Number | IXEH20TT | | OEM Equivalent Part Number | 1611548180, 1N1918110, 224011HC1B, 224018760R, 9091901253 | | Thread Size | 14mm | | Top Material Type | Ceramic | | UPC | 042511471146 | | Unit Count | 4.0 Count | ## Product Details - **Brand:** Denso - **Core Material:** Platinum - **Thread Size:** 14mm - **Top Material Type:** Ceramic - **Vehicle Service Type:** Car, Van ## Images ![Denso Iridium TT Spark Plug - 4711 (IXEH20TT) (4 Pack) - Image 1](https://m.media-amazon.com/images/I/71RjREPZYrL.jpg) ## Frequently Bought Together - DENSO Iridium TT Spark Plug 4 Pack - IXEH20TT - Twin Tip - The Powerful Premium Quality Ultra-Efficient Replacement Plug - FRAM Extra Guard CA10190 Replacement Engine Air Filter for Select Toyota, Scion and Pontiac Models, Provides Up to 12 Months or 12,000 Miles Filter Protection - A-Premium Engine Ignition Coil Packs Compatible with Lexus CT200H 2011-2016 Toyota Corolla 2009-2017 Prius Scion IM XD 1.8L 4-PC Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/536079059-denso-iridium-tt-spark-plug-4711-ixeh20tt-4-pack](https://www.desertcart.vu/products/536079059-denso-iridium-tt-spark-plug-4711-ixeh20tt-4-pack) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-07-04*
