Unfortunately you've got the year that used the specialty plugs. NGK DILFR5C11D are $21.29 on our site. But if you use coupon code IRI10TITAN at checkout this month it will give you 10% off.

Specialty plugs? Well, I know my motor is the same as any 04 or 06 FFV Titan, so can I just get a price for the OEM FFV plugs that are listed for an 06 Titan then? I think the FFV's are iridium

I know when I bought 1-step colder NGK Iridiums for my truck, they were only $43 for all 8. Just figured our OEM heat range Iridiums wouldn't be much more expensive

Yeah, the 2004-2007 Titans had the DILFR series plugs OEM. There's nothing stopping you from installing the standard iridium plugs, but they are a downgrade from the OEM plugs. Nissan commissioned NGK to make this plug specifically for the Titan, so it has some features that were specially made just for that engine. Using a lower grade plug won't cause engine damage, but it does have the likely potential of decreasing performance.

Learned something new. Very interesting. NGK site does show the 04-07 FFV using DILFR5C11D. 08-10 FFV shows as LFR5AIX-11

I know that on every other auto parts site (as well as other Titan sites) the plugs listed for my truck are the PLFR5A-11. I ordered a set for about $100.00. DILFR5C11D never came up on any of my searches. Just saying.

I would say no. The only way that I know for sure is if there is a sticker on the inside of the fuel door. Mine doesn't have one.
