I bought my car from the dealership used and it had a bunch of stuff done to it. How do I tell if I have a spacer and a plenum, its an 05 5at

 

If you have the spacer in your plenum you can see it between the upper and
lower plenum. Do a search in spacer install and you should be able to really
tell what I'm refering to. This way you'll see why we need the spacer for our
'03 thru '05 G35s....Nissan design error!

 

thanks bro will do!
