Default intake manifold elbow

just wondering what you all think about this upgrade. i understand cooler air and more of it is a good thing. not a huge power gain but maybe a little better turbo spool and lower egts as well as a small fuel gain. they are from 280 to 360 dollars. which one offers the best performance? bladerunner, cfm, or ATS? or is it a total waste of $$$$$$$$

My understanding is that it doesnt make a huge difference on a 12 or 24V second gen. But makes a bigger difference on the third gens.

thanks for your input on this. not sure if i will purchase this or not. i like the idea of more cooler air. but if it is not much of a gain if will spend the money on the 3000k governor spring kit instead.

so in other words there is no performance gain at all? i understand what NOS does. but is water/meth going for the same thing. not sure how that one works, so i thought i would ask. i would need new head studds if i were to go that route.

I think your better off spending your money on a good filter and intake and a 4" or 5" exhaust.

i was going to go with 4" exhaust but is was around 550 to 600 bucks turbo back. got 4 different prices all within 50 bucks. then a old boy asked me how much weight do i pull. he said the turbine muffler works like 4" it pulls the exhaust from the motor. he said if i was not pulling over 10000lb it will work fine. i did tons of research online about this product. it all was positive. so i went with it. it cost me 119 bucks. i thought a k&n filter was good. i modified the air box so the whole botton is sucking air(cut it all out) but i'am kinda new to this.
