how can you measure it? I guess my opinion is form what i noticed with my truck, building more boost, quicker. i guess we are all here for opinions.. but i don't think all intakes are a scam....

One way you could measure it is with a scanner.

EFIlive would allow you to measure the number of data frames it takes to say, go from 0 psi to 30 psi.

in fairness, there is one condition that makes an alternative intake important (IMO). Moisture. I would want a foam filter, for example, if I were expecting to encounter a lot of water. The pleated paper filters can load up.

Find the "spicer study"

it is an eye opener to the realities of aftermarket elements.

very informative. One critisism, he didn't use a higher air flow rate for resistance testing, we would benefit from seeing 800 cfm ratings.

To clarify, this study is out of context, it compares swappable elements in the stock box IIRC. It is not an "intake" study

I understand that GM has a TSB out for the LLY airbox. The fix is to replace it with the LBZ airbox which is supposed to be much improved.

thats good info... amazing how they don't let the owners know!!!!

Because you won't get it, unless you have a well documented overheat issue. They are expensive, like $600.

And it is improved. About a 50 degree improvement.
