Autolite Spark Plugs HT1 Platinum | sku-3812929403
No rating yet(0 ratings)This 8 pc set of Autolite Spark Plugs is model HT1, SKU sku-3812929403, UPC 463812929400. The platinum center-wire firing tip is designed to improve performance and durability, while the yttrium-enhanced ground electrode transfers heat. The full platinum tip resists gap erosion.
A necked-down center electrode uses less voltage than a standard plug for easier starts, quicker acceleration and improved fuel efficiency. The high-nickel side electrode maintains the gap, and each plug has a heat-fused, leak-proof resistor. A 4 year limited manufacturer warranty is included.
Autolite began making buggy lamps in 1911 and later moved into spark plugs; by 2007, it had made over 10 billion. The listing also references 7989, HGR9BDP and PZH1F. Listed fitments include the 2005-2008 Ford Mustang, 2006-2008 Ford Explorer, 2007-2008 Ford Explorer Sport Trac and 2006-2008 Mercury Mountaineer, each with an 8-cylinder 4.6 L engine.
