Sp 1989/1990?
 

I recently ordered an Injen CAI for my non-NISMO Z. According to the vendor's part chart, SP 1990BLK would fit a base Z; however, when it arrived every label clearly indicated this part was for a NISMO Z. I figured I'd throw this one out there to see if anyone knows for certain if this part is or is not compatible?? Thanks in advance!
