In my modified magazine i see this Skunk 2 Plenum Spacer it says Dynotested +10HP! Roadtested +3mpg! and i think to my self well hot dam its to good to be true?

Any one who knows there stuff can shed some light on if the +3mpg is truth or pure garbage.

 

I believe that with the Skunk 2 plenum spacer you cannot use the Strut Bar or Engine Cover without making some modifications, I have access to them through one of our dealer accounts but won’t sell them because of this. Go with a Motordyne 5/16" spacer, great product.

i have the spacer, you can feel a little bit in the butt dyno as far as MPG, thats a tough one. im sustained right now at averaging 24.5MPGs. he is right about teh stru bar. i added 2 washers and adjusted the bar to the outmost setting i could get.
