Could somebody please run outside and measure the inside of their air box for me? Mainly want the length and width of the box. Would do it myself but I'm 600 miles away from my garage haha

 

No help? Guess its hard to take off three bolts and a tape measure for people.

 

I just measured mine. 2001 GSR oem airbox (off the car). Measer edge to edge from the top. Got 8" long x 6" wide. Appears to be a little wider in them middle where the top and bottom join.

 

thanks for the measurements. was attempting to find the largest filter that was universal that can fit in our airbox. but after looking around seems all manufacturers go from 5" to about 8" without any between them. K&Ns oem replacement seems to be the best (of course) next is the AEM Dryflow -> K&N 2820. Posted more info on a thread in All Motor thread if anyone has more interest.
