Anyone out here with a 2010 Tundra 4.6 V8 have any experience with after market air intakes? I'm looking around and it seems that Airaid is the only company making an intake for this engine (where is TRD???). I'm thinking about getting an intake system but i wanted to hear from anyone with experience...is there noticable difference in power/fuel economy? Is it worth the $350-$400 to add?
