so i bought a used ss/sc and im still learning things. it has an option b and im wondering if that means it has to have dual pass or not and how i can tell if it does. also what all of this means i already tried searching

 

I believe that if it has option b then it has a dual pass, but I may be wrong. You could send it to me and I can make sure...just cant promise I'll give it back! Lol

 

also don't you have to have an after market HE to have the dual pass end plate and option b? mine is the stock HE

 

I would recommend it since the heat exchanger is a good mod but you can run the dual pass without one

 

You don't need to have a dual pass to run the option B. If you look at the right side of the intake manifold, under the blower, see if there are two hoses coming out of it or if there are three. Two is stock, three is dual pass.

 

ok cool, ill checks this out tomorrow
