I have a 2008 Nissan Titan I purchased several years ago. The truck had a little over 100k miles when I bought it. I don't know the history regarding all the previous maint done. I have done all the things you can do other than spark plugs,brakes,and suspension parts. This is a totally stock truck that currently has 146k miles and running strong!

My question is if I replace all 8 spark plugs should I also install new coil on plug boots?

As a lot of you prob. are, you wanna buy excellent quality parts and at the best price.
For 8 NGK (58913) CPB-N002 Coil on Plug Boots $79.92​
I also found TRQ Engine Ignition Coil Boot Kit Set of 8 Part# ‎ICA30400 for $38.45 + Life time warranty.

I would be very grateful for as much feed back as possible. Thanks!

Dunno about the TRQ's, but the NGK's generally do fine. You don't want to go bargain-basement on COP coils. Nissan ECM's don't use a discrete feedback wire like some other OE's, but they do use current-sensing to evaluate whether COP's have a problem in the primary windings. Cheap coils will often give your engine a case of code-itis.

FYI, Nissan OE coils are all made by Hanshin, and that's a partnership with Denso called Wuxi DENSO Hanshin Automotive Products, Co., Ltd. So when you buy aftermarket Densos, for the most part they're OE's without the sticker.

Im confused! Which one does my truck require ?

With that kind of mileage and an unknown maintenance record, replace the whole coils (top) and not just the boots.
