Fuel economy? Nah didnt really change with the
snorkel, only noticeable difference is mine used to hurt in hot weather!! NOTICABLEY!! Crossing the Nullabor in summer I could feel it slowing/losing efficiency as the air temp got up, but later with the
snorkel the temp differences are no where near as noticable.
The air cleaner, obviously is a hell of alot cleaner, picking the air up higher than from the engine bay.
The other big difference was the 2.5' exhaust, it gave the truck alot more torque, it was audibly asmatic before the exhaust upgrade and this may also be the cause of your resonance. I still havent had it tuned up after the upgrade and that was about 60k km ago. Realistically I should have to benefit from the more flow up top, therefor allowing for more fueling than before.
Good luck with the noise hunt, they can really get to you cant they!!
let us know how you go!
Matt.
