Does anyone know if you are supposed to put the liner under the fender back on for the nismo intake? I helped a guy put on a nismo intake on his 06 and was not sure if you are supposed to put the liner back on. it never said anything in the instructions?

 

What liner are you referring to? Diagram or photo helpful.

 

Yes put it back on. It will keep the filter away from dirt flying from the tires.
