I definitely want to get an intake and it seems like the frankencar is the one to get, and it is apparently worth the extremely long wait times for it... Do you get better gas mileage with the intake installed or not? I couldn't find this in the search...

 

Don't have 1st hand experience, but a friend of mine who has a 2003 Altima has just installed a Frankencar on his 3.5. He's been raving about the sound and the improved gas mileage.
