Attention!!! my friend! Our spark plugs are sold by "piece", not by "box" or "set". Because every buyer's need is different, some buyers only need 1 piece. So please make sure you are buying 1 piece or other quantity before you buy. Thank you for your support and understanding. 1/4Pcs Iridium Platinum Spark Plugs PFR6Y For Roewe 350 550 750 i5 W5 MG3 MG5 MG6 MG7 MG GT ZS MGTF High Quality Size Spanner Size: 16mm Thread Length: 19mm Thread Diameter: 14mm Installation Torque Value: 25-30 OE Numbers PFR6Y Suitable Model FOR FENGXING JOYEAR MPV 1.8 2009-2012 Engine: 18K4G FOR FENGXING JOYEAR X5 1.8 2013- Engine: 18K4G FOR HANTENG X7 1.5 2016- Engine: 15S4G FOR HAWTAI B11 1.8 T 2010-2016 Engine: 18 K4G FOR HAWTAI BOLIGER 1.8 T 2011- Engine: 18 K4G FOR HAWTAI BOLIGER 1.8 T All-wheel Drive 2013- Engine: 18 K4G FOR HAWTAI SANTA FE 1.5 T 2014- Engine: 15S4G FOR HAWTAI SANTA FE C9 1.8 Turbo 2008-2015 Engine: 18 K4G FOR LUXGEN M7 2.0 T 2013- Engine: G20TE FOR LUXGEN MASTER CEO 2.2 T (DYM6481) 2012- Engine: G22TE FOR LUXGEN S5 1.8 2013-2015 Engine: G18TE FOR LUXGEN S5 1.8 (DYM7182) 2013-2015 Engine: G18TE FOR LUXGEN S5 2.0 (DYM7202) 2013-2019 Engine: G20TE FOR LUXGEN U7 2.0 2013- Engine: G20TE FOR LUXGEN U7 2.0 T 2011- Engine: G20TE FOR LUXGEN U7 2.2 T 2011-2013 Engine: G22T FOR LUXGEN U7 2.2 T 2013-2015 Engine: G22TE FOR LUXGEN U7 2.2 T 4WD 2013-2016 Engine: G22TE FOR LUXGEN U7 2.2 T 4WD 2011-2013 Engine: G22T FOR MG (NANJING) MG3 SW 1.4 2008-2011 Engine: 14N4S FOR MG (NANJING) MG3 SW 1.8 2008-2010 Engine: 18N4S FOR MG (NANJING) MG7 1.8 2008-2008 Engine: 18N4S4 FOR MG (NANJING) MG7 1.8 Turbo 2007-2014 Engine: 18 K4K,18N4T FOR MG (NANJING) MG7 2.5 2007-2010 Engine: 25V6S1 FOR MG (NANJING) MGTF 1.8 2007-2013 Engine: 18N4S FOR MG (SAIC) 3 1.3 2011- Engine: 13S4F FOR MG (SAIC) 3 1.5 2017- Engine: 15S4C FOR MG (SAIC) 3 SW 1.5 2011- Engine: 15N4S4,15S4U FOR MG (SAIC) 5 Hatchback 1.5 2012-2017 Engine: 15S4G, 15S4U FOR MG (SAIC) 6 Hatchback 1.8 2009- Engine: 18K4C FOR MG (SAIC) 6 Hatchback 1.8 Turbo 2009- Engine: 18K4G FOR MG (SAIC) 6 Saloon 1.8 2011- Engine: 18K4C FOR MG (SAIC) 6 Saloon 1.8 Turbo 2009- Engine: 18K4G FOR MG (SAIC) GT 1.5 2016- Engine: 15S4C FOR MG (SAIC) GT 1.5 TCI 2014- Engine: 15S4G FOR MG (SAIC) ZS 1.5 (CSA7151) 2017- Engine: 15S4C FOR RELY H3 2.0 2010-2011 Engine: SQR484B FOR RELY H5 2.0 2010-2013 Engine: SQR484B FOR RELY X5 2.0 Turbo 2011-2014 Engine: SQR484B FOR RELY X5 2.0 Turbo All-wheel Drive 2009-2014 Engine: SQR484B FOR RIICH G5 2.0 Turbo 2009-2014 Engine: SQRE4T20 FOR RIICH G5 2.0 Turbo 2009-2011 Engine: SQR484B FOR RIICH G5 2.0 Turbo 2010-2011 Engine: SQR484J FOR RIICH G6 2.0 Turbo 2009-2014 Engine: SQRE4T20 FOR ROEWE (SAIC) 350 1.5 2010-2018 Engine: 15S4U FOR ROEWE (SAIC) 350 1.5 T 2013- Engine: 15S4G FOR ROEWE (SAIC) 360 1.5 2015- Engine: 15S4U FOR ROEWE (SAIC) 550 1.8 2008- Engine: 18K4C FOR ROEWE (SAIC) 550 1.8 Turbo 2008-2013 Engine: 18K4G FOR ROEWE (SAIC) 750 1.8 Hybrid 2011- Engine: 18K4G FOR ROEWE (SAIC) 750 1.8 Turbo 2007-2008 Engine: 18K4G FOR ROEWE (SAIC) 750 2.5 2007-2015 Engine: 25K4F FOR ROEWE (SAIC) i5 1.5 2018- Engine: 15S4C FOR ROEWE (SAIC) W5 1.8 Turbo 2011- Engine: 18K4G FOR ROEWE (SAIC) W5 1.8 Turbo All-wheel Drive 2011- Engine: 18K4G FOR ROEWE (SAIC) W5 3.2 2011-2014 Engine: G32D FOR YEMA T70 1.8 2015- Engine: 18K4G FOR ZOTYE DMX7 1.5 2017-2017 Engine: 15S4G FOR ZOTYE T600 1.5 2013- Engine: 15S4G Package Included 1/4 x Auto Spark Plugs Automotive spark plugs are available in the following materials: 1Nickel alloy.
