I have gone through numerous threads in regards to adding the MREV2 and 5/16 spacer to an Injen CAI... will this combination increase power??? will it be power that i can feel??? will it mess with my gas mileage??? Please, anyone who knows the correct results post a reply. thanks.

 

do you have a rev up or non rev up engine?

IIRC non rev up engines should use the mrev2 only (without spacer) as the two together will cause you to run lean

as for gas..helll no youll be getting worse mpg lol..youll be mashing out all the time to hear the sweet noise it makes

unless you are a really controlled and conservative driver then it shouldnt affect your mpg..
