im pretty much doing an experiment. i'll be locking my tC every full tank to see if anything i change/add will effect the gas millage. i'll try to drive consistently.

i'll probably start with a intake.
K&N a good choice?
a good website to get them?

 

Im guessing you're talking about an intake filter?

If so, you can probably get them locally at an auto parts supplier...

 

yeah but a K&N high air flow performance reusable filter.
