They all say that but you wont 
The Isuzu stuff sold here is all intended for the diesels. I have an Airtec on my Rodeo ute, which looks a lot like this except the under guard pipe is hard plastic too.
You DO get the cleaner cooler air, but they dont flow enough for the V6. Just unclipping the airbox top off the lower on our dyno leaving the filter in place gained 7hp over breathing via the snorkel, and 12hp on the supercharged 3.5.
So I run two airbox entries for the street and close one and use only the snorkel for the dirt. I'm usually in low range anyway so it doesnt matter
The answer is more power! What was the question?
