TRD Cold Air Intake if I have a TRD Air Filter

So I'm looking at jumping on this TRD CAI group buy that ends in a couple days but reading a couple of reviews, I'm not sure exactly what the product entails. I have a TRD Air Filter on my 09 and am wondering if the CAI already has a filter build in that would take the place of the TRD Air Filter I have now......or will they work together. A couple of reviews on the forums say a different things.......I'll keep searching for answers, just wondering if anyone could help me out. Thanks guys

 

its going to replace your stock air box an TRD filter with a better flowing air box an TRD filter

 

So I will have to ditch the TRD Filter? Will a see a benefit that can justify the product?

 

Right now you just have the TRD drop in filter right?

cause you will be replacing that with this. (see pic) An yes you will see a little more HP an better MPG. not much but some...

Does the clear lid come on the new ones OR is it a mod lid?
