I have a 2005 300C AWD. Love the car, but am getting 17-20MPG with mostly highway driving. I have been considering upgrading the cold air intake and the exhaust. Always interested in more power, but I have been told both can improve mileage as well. Has anyone seen improvement in said after said mods were made?

the stock intake is actually one of the best intakes u can have on your hemi... there was a great intake face off on a sister site... u should check it out... i think i'd only get the mopar one now b/c i do like to hear more of a rumble... but, i'm not doing it for mpg b/c it shows that none of them help within the 10-15mpg that they claim to give...

here is that forum and the resluts...

Thanks, good site. Looks like there may be a slight improvement in mpg, but may not be worth the effort.
