OldSlowReliable Posted July 9, 2010 Share Posted July 9, 2010 Put the factory box on instead of my cone filter. Got a new fram air filter all set and ready, its in and everything is closed/tightened BUT I start it up, and it sounds like its running normal, but when I hit the gas to rev it up a tad, when it falls in rpms after I take my hand off the throttle, it makes this crazy fluttering sound, kind of like slowing a car down via a lower gear if you know what I mean Link to comment Share on other sites More sharing options...

nismothunder Posted July 9, 2010 Share Posted July 9, 2010 If its fluttering then it does sound like you have a leak someplace,or the filter is letting air get past it.I have run mine with out a air filter and it sounds like a mega whoshing sound.

Tungsten Posted July 9, 2010 Share Posted July 9, 2010 the filter isn't sealing inside the box Link to comment Share on other sites More sharing options...
OldSlowReliable Posted July 9, 2010 Author Share Posted July 9, 2010 The $10 fram air filters have done good by my book, cheap and filter just fine as far as I can tell. the filter isn't sealing inside the box That would make sense, my box is sort of warped and it was hard as hell to get it in there, its probably not covering an edge. Ideas on how to fix this due to a 3" body lift? I can barely lift the top half all the way off Link to comment Share on other sites More sharing options...

I know its not in backwards (seriously? people do that? lol) I put all the tubes back on, but the most forward fender inlet has a broken push pin thing so its not sealed very well on that connection where it clips to the fender. It was most definately from the air box, but it caught my attention because it sounded like a fart can after revving the engine. Link to comment Share on other sites More sharing options...
Precise1 Posted July 9, 2010 Share Posted July 9, 2010 Ideas on how to fix this due to a 3" body lift? I can barely lift the top half all the way off Unbolt the bottom support bracket on the engine side allowing the box to sag on that side and tilt the entire unit. It doesn't make it perfect, but it helps a lot... B Link to comment Share on other sites More sharing options...
