Perfect fit for most threaded oil fill ports on Honda and Acura vehicles along with some Ford vehicles that use a threaded style oil filler cap Advanced Engine Oil Funnel attaches directly to the oil fill port in place of the oil cap The funnel seals just like the factory cap to avoid spills The funnel doesn't need to be held leaving you with both hands to open oil bottles and refill the engine Made from durable materials What This Advanced Engine Oil Funnel Fits This funnel fits most Honda and Acura vehicles along with some Fords that have a threaded oil filler cap.  These oil filler caps have threads that measure about 1-1/4" (1.25") in diameter on the outside.  For Ford vehicles, this will fit many early model engines as well as some later model Super Duty and Mustangs.  It will not fit most late model Fords as they use a 1/4 turn style cap.  We highly suggest checking your cap before ordering.
