do a search. they are useless on these engines, you will actually lose power from it.

 

-2hp Don't bother. Go ahead with the CAI and instead of spending the $100 on the spacer go out and get a flowmaster (or whatever brand you prefer) muffler. Do a search on performance and you will get tons of info.

 

Using the search tool on this site will be your biggest advantage.

 

Oh Really? Well i installed the one from airaid from summit racing and gained almost 2 mpg and better throttle response too.

Yes i agree that the fuel is added after the spacer but all i know is without it i get 14.9 mpg and with it i get 16.8. Dont ask me how but it improved for me.

 

Overhead MPG's...

Or.. hand calculated....

Cuz those things are useless....

 

He only thinks he is getting better. Isn't happening.

Hand calculated 6 different times. You know some of you guys kill me, you have no idea about my experience as a mechanic and such and treat some people like total freaking idiots. I have been an ase certified master truck mechanic for over 20 years so please dont treat everyone like a total noob about this stuff ok?
