I noticed a difference.

 

I bought the non drop base and then had to buy a 1" spacer for the tbi because the breather wasen't clearing the map sensor bracket also egr.. now with 1" tbi spacer the bottom of the breather just touches the plug for the map..

I'm also using k&n 14x4 element! btw it's on a 1/2 ton truck..
