Keep in mind in the ads,
The Xterra is listed at "rugged", not sporty..
Don't expect Nissan to do alot of aftermarked power stuff for it..
As a "rugged" truck, the engine is tuned for torque, hot peak hp..
The 3.3 is a really old design.. Not surprised there is not alot of money spent on hop up parts..
When the 4.0 comes out in a few months, (I am guessing) there will be alot of aftermarket support for power stuff.. look at the Titan..
how long has it been out, and already Toys!!
