73mm C&L
 

I am wondering how big of a performance difference 73mm to 77mm mass air housing would be. Summit has the 73mm on sale for $125 now, so is it worth it or should a guy spend at east $100 more on a larger one?

BOTH mass-air meters work well,just make sure that the meter matches whatever fuel injectors your using.

Well to be frank it depends on the power level your looking for.

Mine works fine for me. It's still bigger than your throttle body so I wouldn't expect it to be a bottle neck unless you had a bigger tb. Then again, that thought process could and probably is wrong. I think you can get them cheaper through Vortech directly on their website. That's where I got mine. Maybe not anymore though.
