This is one of the few things where I think OEM items are the best bet. Plus, I think OEM plugs for the T are iridium to begin with. I haven't replaced mine yet, but when I do, it will probably be with the NGK's if that's what the OEM's are. I know my wifes Maxima had NGK's stock and I tried something different and the thing ran like crap and I went through a couple of coil packs. Related, not sure, but after going back to the NGK's, I had no issues.
I'm just assuming that the Titan uses NGK Iridiums. I can look it up just to confirm.

I think the FFV Titans have NGK iridium plugs, whereas the gas-only Titans have NGK double platinum plugs. Either way, the OEM plugs are the best option IMO.

I use the E3 for my lawn equipment, never seen these plugs for the truck
yes the OEM NGK's are your best bet for replacement

So that's 3 for OEM and 1 each for E3 and Bosch +2 or +4. Intresting...
I ran Bosch +2 in my wife's saturn and she complaind about it for three weeks because she had to get use to the torquey launch from the light when she was at an intersection. She said it accelerated like a mad man. I put a lot of weight in that because I didn't tell her I was swapping her plugs - no placebo efect. I wanted to run them in my Xterra but let the general population talk me out of them. "They" said the NGK copper was the best. Ran the NGK Copper in the X for a year and then my coil pack crapped out. Could have been a coincidence, could have been the NGK.
Either way. I feel OK about the Bosch, but the E3 remains a bit of an unknown to me. If I go with stock OEM, I'll just leave the original ones in there. Truck only has 47k.

NGK copper for the win. Iridiums are not a good conductor of electricity especially on boosted setups...so stay away from the hype.
Speaking of Plugs, what are the factory plugs gapped at, because I was curious about running my Kenne Bell Boost a spark which works great on my Turbocharged Ka24de 240sx for ignition break up at higher rpms. The BAS allowed me to gap my plugs from the originally .028 gap to around .045 without any issues and the car pulled harder, ran stronger and sounded better. I don't have a dynosheet to prove yet but I will soon.
Granted I know the factory COIL ON PLUG setup on the titans is incredible even for boosted setups, I was just curious if say I good gap the plugs up to around .060 or higher with the Boost A Spark and see if it increased driveability.
I'm sure its pointless since i'm not forcing air into the cylinders via turbo or supercharger, but who knows never know till I try it out.

Yeah, I like the longevity of iridium, but you are right. Copper conducts much better. Technically nothing conducts like silver, but you can't make a plug out of it. Aside from the heat that would melt it from combustion, just sparking alone would erode the electrode. Mercury conducts good too, but metals at a liquid state when at room temp are a no go.

I noticed in your avatar you are a "TKE", I had a friend who was in that frat at university of west florida, unless I am completely mistaking your avatar. Needless to say we had some hella awesome drunken college girl entertained parties lol oh the booze of college. wait..i'm not even finished with college yet, YES!

our 2008 trucks use the NGK Iradium plugs, the gap is set at .43(1.1)

That is correct, they should be ready out the box. If one looks off compared to the others then get it exchanged.
Don't try and gap them yourself unless you have the special tool for Iridium type plugs, you will damage them trying.

Anymore info? Man, I didn't know all this. So FFV Titans run iridium plugs? Nice. So NGK Iridiums are the way to go for me then. What would be the harm of putting Platinum plugs in my truck?? Is their no point? Copper, so its good for cunductivity, maybe I should try them, how long do they last?

When I bought my Titan I did a lot of research on plugs becasue like many here it seemed confusing. What I found out:
Double Platinum (platinum at both spark contact points) are recommended as they have a long life. You can run the single Platinum but plan to change out sooner. Iridium is used for extreme long life. If double Platinum gets you 100,000 miles, Iridium is supposed to get 150,000 miles.
If you never run E85, you can use the common Platinum/double Platinums in your FFV Titan. Apparently Nissan also specified a particular metal coating on the factory NGK plugs for FFV Titans as denoted by the "D" at the end of the plug code. I have not confirmed this but suspect it resists the corrosivity of the E85 a bit better.
As I have no problems changing out plugs sooner than later I recenlty put in the NGK single Platinum LFR5AGP with 0.44 gap with 60,000 miles on the engine. Stock PLFR5A-11D's had a slight bit of build up. New plugs really smoothed out the idle, driveability and improved throttle response. I would never wait till 100,000 miles to change out the factory double Platinums so running the less expensive single Platinum sis good enough for me.
This is the info I have come across. Do your homework before making your own decison (the caveate).

Regareding E3's
There was lot of ealry hype. I picked up a few to run in my snowmobiles as I drag race them and am always looking for an edge. They seemed to work a tiny bit better, but I noticed on a couple the ground strips were falling apart. Have since abandoned the E3's and gone back to Iridiums on the sleds. A lot more consistant and take a beating without any concerns of them falling apart.
Starting to think the plug manufacturers have figured out that "high performance" plugs are a new way to pull dollars out of our pockets.

Did you ever find out what the "D'' stands for at the end of the spark plug model?
My titan is about to turn over 55k miles so I guess its time to throw some new plugs in soon.
