Fipk or 77 series........... Differences other than the tube? What one works better on the hemi's, just wondering caus eim looking in to a intake and my buddy just put one on a tundra, with a metal tube and it sounds mean. Thanks

 

I think the metal tubes make more noise and heat up more. The heat usually doesn't matter as the air doesn't stay in the tube long enough to heat up and I like the look of the metal one better.

 

$300 for 8hp. Just get a K&N drop-in filter and be done with it. All you will really gain is intake noise unless you have a lot of engine mods.
Even the K&N add says 8hp for the Hemi Ram.
