Re: [Chrysler300] does it really matter, heat tube functionality

[Mike Apfelbeck <moparmike@xxxx>]

Engines run with manifold heat warm up better, have better driveabilty, and 
get better gas mileage. The "hot spot" in the manifold is sized so that it 
is cooled off by the extra fuel/air flow during high speed running, and 
doesn't affect top end power to any easily measured degree. You can do 
without it if you don't mind extra raw gas washing down the cylinder walls, 
shorter spark plug life and crappy inefficient running around town.
