i bought an 06 cobalt ss about a week ago and i orderd a heat exchanger kit, CAI, vibrant header+downpipe, and the ott performance stage 1 s/c kit. i saw the dual pass endplate with the option b kit and i really dont know what it is to be honest.. Can anyone explain this to me please?

Thank you

 

Search "Dual Pass" you will find a lot.

Stock intercooler is 4 pass, the dual pass end plate allows it to become 2 (dual) pass. Option be is a larger coolant tank that the filler neck. All this helps drop IAT2's (intake air temperature after the blower).

 

thanks i tried searching it, im still a little unsure about buying it because of my lack of knowledge about it but ill keep looking into it.

 

i would highly recommend the dual pass. the more cooling mods the better. doesnt matter whos you buy, the all do the same thing

and instead of the option b i would say do the hatrickstu mod. search for that and you will see what i am talking about. easy to do and better then the option b in my opinion.

 

thanks for your help guys, i guess more what i was asking is how do you install the dual pass end plate and do i need an option b kit with it?

 

To install the dual pass you need to pull your blower and intake manifold. flip some of the laminova cores. Install the end plate, put the intake manifold and blower back on. Then re route the houses. No you do not need option B, there is an option A, which utilizes the stock filler neck instead of the "B" tank. There is a couple how-to's on this I believe.

 

I would say get it, it really helps!!

 

I made my own... very easy to do. Only paid 45 bucks for hose, clamps, and some brass elbows.

 

You got any links to those How to's? I'd love to see them

 

I also made mine, with a little help from my dad's welding and grinding machine.. was free for me, had the stuff laying around.
