ok one is $100 cheaper than the other and they both seem like the same thing. does anyone know performance wise if theres any difference?

 

UPD has shitty quality. K&N is pretty tough from what i hear.

 

I just ordered the K&N drop in and the airaid tube. I got the K&N at my house now, gonna have the MIT tube on Wednesday. I'll let you know the results later in the week. But, I can't compare my results to the UPD.

I would think the UPD would have slightly better results due to the shape of the replacement lid.

Yea im going with a K&N drop in and the MIT tube looks good enough for me.
