I know this is reviving an old thread, but I have recently been looking for a Nissan factory "Engine Block Heater" for my Titan.
I am the Parts Manager at an Infiniti dealership and see that the part# listed in the above DIY pictorial (999M4-YA001) has since been discontinued. There shows to only be one dealership (Anchorage, AK) in the entire country that still has one in stock.
Since then, I have done some investigating and today found some parts that appear to be correct for what I am looking for.
Location: Winchester TN Ten minutes from the Nissan Powertrain Assembly Plant
I worked on the 5.6 assembly line from 2004-2008 and we installed many of these block heaters. I work on the 2.5 assembly line now and it looks to be the same heater used on the previous model used in the 2007-2012 2.5.
2008.5 Titan CC LE FFV, rear drop, k&n cai, flowmaster 50 series, 5% tint, all emblems removed, Two POLK audio 12s
