I was wondering if adding a spacer to a b series motor is worth the time and money, I keep hearing it will increase power up to 20 horsepower, but not sure. I was thinking of getting an obx or helix spacer. I think they do the same thing but the insides are designed differently, so i guess it controls the flow alittle. Does it work?

 

get the tornado while you are at it. Sorry had to do it. CAI better get 50hp then. To answer your question, no.
