{"product_id":"ngk-spark-plug-28","title":"NGK Laser Platinum Spark Plug PFR6X-11 for Audi A4 Quattro, A5 Quattro, A6, Q5, and S5 (2008–2012)","description":"\u003cp\u003eThe NGK 5757 Laser Platinum spark plug, NGK designation PFR6X-11, is a platinum-center-electrode plug for the Audi A4 Quattro, A5 Quattro, A6, Q5, and S5. It has an M14 x 1.25 thread with a 19 mm thread length and installs with a 16 mm spanner. The platinum center electrode works with a single ground electrode, and the spark position sits 3.5 mm out from the seat. A 1 kOhm internal resistor provides interference suppression, which keeps ignition noise out of the vehicle's electronics. The plug seals on a gasket seat and has a fixed SAE terminal, so there is no removable top nut to back off or tighten. NGK makes this plug in Japan.\u003c\/p\u003e\u003cp\u003eThis spark plug carries a 24-month, 24,000-mile warranty.\u003c\/p\u003e\u003cp\u003eThe 5757 cross-references to Audi part numbers 101905611A and 101905631F. Either number on your old plug or in an Audi parts lookup is a good sign this is the right plug. Audi uses different plugs across its engines, and two plugs with the same M14 thread can still differ in thread length, resistor value, or electrode material, so compare the PFR6X-11 code and the 19 mm thread length against the plug you remove. A spark plug carries high voltage from the ignition coil across its gap to light the air-fuel charge in the cylinder, so a worn plug shows up quickly in how the engine runs.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: NGK, a brand of Niterra Co., Ltd. of Nagoya, Japan\u003c\/li\u003e\n\u003cli\u003eNGK part number: 5757\u003c\/li\u003e\n\u003cli\u003eNGK designation: Laser Platinum PFR6X-11\u003c\/li\u003e\n\u003cli\u003eThread: M14 x 1.25, 19 mm thread length\u003c\/li\u003e\n\u003cli\u003eSpanner size: 16 mm\u003c\/li\u003e\n\u003cli\u003eElectrodes: platinum center electrode, one ground electrode\u003c\/li\u003e\n\u003cli\u003eInterference suppression: 1 kOhm resistor\u003c\/li\u003e\n\u003cli\u003eSpark position: 3.5 mm\u003c\/li\u003e\n\u003cli\u003eSeat and terminal: gasket seat, fixed SAE connector\u003c\/li\u003e\n\u003cli\u003eCross-references: Audi 101905611A and 101905631F\u003c\/li\u003e\n\u003cli\u003eMade in Japan\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months or 24,000 miles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat symptoms point to worn spark plugs?\u003c\/strong\u003e\u003cbr\u003eMisfiring, a check engine light, hesitation, loss of power, and poor fuel economy are the common signs of plugs past their service life.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this plug seal with a gasket or a tapered seat?\u003c\/strong\u003e\u003cbr\u003eIt uses a gasket seat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich Audi part numbers does this plug match?\u003c\/strong\u003e\u003cbr\u003eIt cross-references to Audi 101905611A and 101905631F.\u003c\/p\u003e\u003cp\u003ePMB Performance sells NGK ignition parts for European cars, backed by more than 20 years of parts experience.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCheck the fitment table below for the Audi models and years this plug fits.
