# Dinan N20/N54/N55/S55/N63/S63 Iridium Spark Plug - Heat Range 9 - 12mm x 26.5mm x 14mm (HV) - SINGLE Dinan Iridium Spark Plugs are an excellent upgrade for tuned, and even stock engines, where applicable.\* Our spark plugs are made from Iridium - one of the strongest materials available. They last longer than other materials with higher melting points, run cooler, resist preignition, and even require less voltage to produce a strong spark. The iridium electrode with its copper core is harder and stronger than other materials, can dissipate heat more easily, and is better protected from melting, cracking, and other limitations found with standard plugs. - 152% higher melting point than silver, 125% higher than copper, and 38% higher than platinum - Heat range 9 spark plug (Similar: Bosch 3, Brisk 10, Champion 4, Denso 27, and NGK 9) - Acceptable for high performance / tuned and most stock\* vehicle applications alike - Optimized electrode design for hard to ignite fuels, such as ethanol - Cooler operating temperature than stock plugs - Resists preignition better than stock plugs - An excellent match for Dinan ignition coils - 1 step colder than OEM (N20, S55, N63, S63) - Stronger than copper and platinum - Lower required supplied voltage - 3 Steps colder than OEM (N54) - 2 steps colder than OEM (N55) - Insulator Material: Ceramic - Projected insulator design - Thread diameter: 12mm - Install Torque: 17 Nm - Thread reach: 26.5mm - Hexagon: 14mm Bi-Hex - Supplied Gap: 0.5mm - Terminal Type: Nut - Seat Type: Flat - Made in the EU This Part Fits: Year Make Model Submodel 2011 BMW 1 Series M Base 2008-2013 BMW 135i Base 2013 BMW 135is Base 2014-2016 BMW 228i Base 2015-2016 BMW 228i xDrive Base 2013-2018 BMW 320i Base 2013-2018 BMW 320i xDrive Base 2012-2016 BMW 328i Base 2014-2016 BMW 328i GT xDrive Base 2013-2016 BMW 328i xDrive Base 2007-2015 BMW 335i Base 2014-2016 BMW 335i GT xDrive Base 2009-2015 BMW 335i xDrive Base 2011-2013 BMW 335is Base 2007-2008 BMW 335xi Base 2014-2016 BMW 428i Base 2015-2016 BMW 428i Gran Coupe Base 2014-2016 BMW 428i xDrive Base 2015-2016 BMW 428i xDrive Gran Coupe Base 2014-2016 BMW 435i Base 2015-2016 BMW 435i Gran Coupe Base 2014-2016 BMW 435i xDrive Base 2015-2016 BMW 435i xDrive Gran Coupe Base 2012-2016 BMW 528i Base 2012-2016 BMW 528i xDrive Base 2008-2016 BMW 535i Base 2010-2017 BMW 535i GT Base 2011-2017 BMW 535i GT xDrive Base 2009-2016 BMW 535i xDrive Base 2008 BMW 535xi Base 2011-2016 BMW 550i Base 2010-2015 BMW 550i GT Base 2010-2017 BMW 550i GT xDrive Base 2011-2016 BMW 550i xDrive Base 2012-2018 BMW 640i Base 2013-2019 BMW 640i Gran Coupe Base 2014-2018 BMW 640i xDrive Base 2014-2019 BMW 640i xDrive Gran Coupe Base 2012-2018 BMW 650i Base 2013-2019 BMW 650i Gran Coupe Base 2012-2018 BMW 650i xDrive Base 2013-2019 BMW 650i xDrive Gran Coupe Base 2011-2015 BMW 740i Base 2011-2015 BMW 740Li Base 2013-2015 BMW 740Li xDrive Base 2009-2019 BMW 750i Base 2010-2019 BMW 750i xDrive Base 2011-2012 BMW 750Li ActiveHybrid 2009-2015 BMW 750Li Base 2010-2015 BMW 750Li xDrive Base 2010-2015 BMW 760Li Base 2011-2015 BMW Alpina B7 Base 2017-2019 BMW Alpina B7 xDrive 2011-2015 BMW Alpina B7 xDrive Base 2011-2015 BMW Alpina B7L Base 2011-2015 BMW Alpina B7L xDrive Base 2016-2018 BMW M2 Base 2019-2021 BMW M2 Competition 2014-2016 BMW M235i Base 2015-2016 BMW M235i xDrive Base 2015-2018 BMW M3 Base 2015-2020 BMW M4 Base 2019-2020 BMW M4 CS 2016 BMW M4 GTS 2013-2016 BMW M5 Base 2012-2018 BMW M6 Base 2014-2019 BMW M6 Gran Coupe Base 2013-2015 BMW X1 sDrive28i 2013-2015 BMW X1 xDrive28i 2013-2015 BMW X1 xDrive35i 2015-2017 BMW X3 sDrive28i 2011-2017 BMW X3 xDrive28i 2011-2017 BMW X3 xDrive35i 2016-2018 BMW X4 M40i 2015-2018 BMW X4 xDrive28i 2015-2016 BMW X4 xDrive35i 2010-2013,2015-2018 BMW X5 M 2014-2018 BMW X5 sDrive35i 2009-2010 BMW X5 xDrive30i 2011-2018 BMW X5 xDrive35i 2011-2019 BMW X5 xDrive50i 2010-2019 BMW X6 M 2015-2019 BMW X6 sDrive35i 2008-2019 BMW X6 xDrive35i 2008-2019 BMW X6 xDrive50i 2012-2016 BMW Z4 sDrive28i 2009-2016 BMW Z4 sDrive35i 2011-2016 BMW Z4 sDrive35is ## Details - **Price:** 52.82 CAD - **Vendor:** Dinan - **Type:** Spark Plugs ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 52.82 CAD | In stock | ## Images - Photo - Primary - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/dinan-n20-n54-n55-s55-n63-s63-iridium-spark-plug-heat-range-9-12mm-x-26-5mm-x-14mm-hv-single) > Updated: 2026-07-05
