I was wondering if those of you who have done this mod could post the gains (or losses) to your gas mileage. I know that its been hard for some with the sudden weight gain to their right foot! I'm kicking around doing this mod and am curious.

Thanks!

 

I did the ISR mod almost 2 years ago. I did it not in hopes of any performance gains. After my body lift, my stock intake was so old that it just cracked apart. So I only really did the mod instead of paying more for a used stock intake.

I noticed a mild increase in throttle response, but the real constrictions in the intake is the AFM

I did get a really nice looking intake for about $25 and an hour of my time. It freed up aLOT of room, and it also made my oil dip stick very easy to access (stock intake blocks it with a body lift).

I would do it just to clean up the engine bay....
