What does a power wire do for a Hemi? Where can I get one for a 07? Is it any good? Thanks.

 

I've never heard of one.

 

he's talking about the Power Wire that Air Ram makes....

all it does is trick the computer into thinking the air coming into the engine is colder then it actually is....should work pretty good cause it will advance the timing just a little bit and possibly a little more fuel (not sure at the moment...gotta get some sleep and get back to ya on that one) you can get em at www.airram.com but last i talked to him he was still in Iraq and wouldn't be back untill sometime around September i believe

 

waste of money IMO... better to get the incoming air colder than to fool the PCM...

 

Bought one....

Tried it.....

Didn't do anything for me but turn the check engine light on every morning.....

Good thing I have the OBDII to clear the code, cause Ida got sick of lookin' at that light all day....

I felt little or no difference in performance. Maybe that cause I've got the 4.7L Magnum rather than the HEMI.

 

Works great for me!! Track and dyno tested!!!
