A few months back I bought a K&N filter (just the filter that fits in the stock airbox) and have no problems with it, however I was curious if the difference in performance/sound/fuel efficiency between a filter and full intake (K&N, Nismo, or Volant) is significant enough for me to spend 200 bucks on.

If you dont mind the noise it makes it has made a lot of difference in the power but not as big of a difference in the mileage, hope this helps.

Did you actually take the truck to a dyno for a before/after test, or to a drag strip?

I have found the K&Ns ALONE just make more noise, and the claimed 10hp cannot REALLY be felt in the "seat of the pants".

A combination of Intake/exhaust AND a computer chip seems to be the best way as the timing needs adjusted with the greater intake-exhaust flow.

Not even sure that 25-30hp claimed with all 3 will be that big of a deal. Maybe .1 off a 0-60 time?
