Fuel economy improvements?
We just bought a 2009 H3 with the 3.7 I5 and was wondering what is the best way to improve the fuel economy that is cost effective?:confused:
Also any ideas on the best grille guard for function and not just looks? |
I replaced our stock filter with a AEM Dryflow one and got 20MPG from Punxsy, Pa to Cincinnati, Oh. $40 for a 100K Mile filter that needs no oil and just washes out.;)

Get the air doc intake and computer programming
if u don't want to spend alot of money |
Thanks for the help. I looked into the Air Doc and it looks reasonable.
I also looked into the K&N cool air intake and they boasted 10 hp gain @ about 4700 RPM, but who in their right mind would run their H3 @ 4700 RPM for any length of time, so the K&N looks like a waste of money. |

The cheapest start is running with your tires all inflated to 38-40PSI cold, then add an OEM performance filter replacement. Then you could look at an Intake, PCM tune, and CAT back exhaust in that order, if you want to do even better.

to be honest driving around the city i usualy get 10-12 mpg. which is rubbish. but driving properly and using cruise control etc... i can get it upto18ish easily. 20 would be a dream lol

Well Worth it
I added a Borla Cat Back Exhaust and a K&N Intake.
I see about a 2-3 MPG Difference. Depending on my Driving. Was it worth the amount of Money I spent? Not for MPG but the Sound and increase power at the top end are well worth it. |

I average a hair above 18 around town. Short trips on the expressways I get around 22, though I haven't taken it on a long trip yet. I'll report back in a couple weeks. This is a stock '08 H3 with stick shift.
