Installed on my 15 year old JKU. As far as performance gains go, going crazy isn't enough. It does seem to help torque a bit as acceleration is smoother in high gear/low rpm. He's been gone long enough to comment on fuel efficiency. The main reason I wanted this was to help with air intake temperatures as we all know how our Jeeps get a bit warm. My gauges say it's dropped about 10F (I live in Louisiana, which is very hot and humid), so any improvement here is all I'm worried about. Get it if you don't plan on going with a snorkel, but if you really need to spend money elsewhere on the jeep, do it first and save for later/if ever.
