curious as to how they have been working on the frontiers.

trying to do a little research on engine mods for the newer frontier motor and found this site

granted, it is a bunch of racers w/ dropped and custom trucks but they seem to be somewhat usefull in the performance section

did a little more research and found this

Nice personal dialogue!

Good finds, but I think the stock engine has plenty of power. Like the guy said... its worth the added grumble.

As with most of these devices, they help over 2500 rpm. Probably won't help with fuel mileage. It would be a performance mod only. No help at low rpm. I will stick with the factory setup on mine until someone comes up with better filtration and some help with lower rpm.
