Are there any mods to improve mpg in a Cayenne S....I picked up a 06' Titanium S last week and was looking at a few mods but want to know if there are any that improve mpg. I know when I added intake and exhaust to my rx8 it gain about 2mpg from the better efficiency.

Oh love the new Cayenne too! It's alot more fun to drive than either of the Mercedes I had.

 

But when you add intake and exhaust, then for some reason after your foot gets heavier and no more added mpg

 

congrats on the car, which color combo did you go with?

 

Thanks, it was the Iceland Silver/Black and steel grey interior....I like black better but was tired of having three black cars.

 

MAYBE YOU COULD RETROFIT THE O8 ADVANCEMENTS ONTO YOURS

E..G. NEW FUEL INJECTION METHOD ETC

 

I doubt he wants to buy a new fuel system, fuel lines, injectors, heads, etc.

 

Yeah if I was that worried about it then I would of just gotten an 08'...I really am just looking for an excuse to do a few mods...it's the wife's car but I still drive it more than she does.

 

Intake and exhaust will certainly help. Also properly aired up tires, avoid oversize wheels...
Make sure it has new-ish plugs and keep her waxed
