Pros: Nice design, mostly spotless welds, nice increase in airflow.
Cons: Too expensive for what you get. Gets a bit hot underfoot inside the cab from the heat generated by the header.
Comments: Tough one - yes there is a difference in throttle response, in horsepower, in fuel economy, BUT ONLY AFTER YOU INSTALL ALL RELATED COMPONENTS. I bought the Banks "power pack" which includes the header, the intake, and the exhaust.
I put the intake on 1st for a couple of months. All I noticed was a huge sucking sounds when I stepped on the gas - nothing else.
Then I installed the exhaust. It made a bit of a difference now as the sucking sound from the intake was reduced and throttle was more responsive and the "butt dyno" was awakened from the typical Jeep slumber.
Then a few months later I installed the header. My holey cow, what a difference. Sucking sound from intake: GONE. increased power, increased throttle response, increase MPH, increased guttural exhaust note = ALL THERE.
Still, was it worth $1100 total? NO.... but... now with *hopefully* the supercharger coming in it the airflow can be used up to it's potential.
