Perfect fit for 2004 G35 "Nismo" CAI
I ordered this to replace the oiled filter on my Nismo CAI (actually we all know the truth now: it's a re-branded AEM!) for my 2004 G35 Coupe. The AEM site does indeed have a list of all their filters, but it's a HUGE list with some subtle differences and their support wasn't very responsive when I asked to confirm the right part number for this specific application. If you want to be sure like I did: It's a perfect fit!I was excited to move to the dry-flow since it's easier to clean, comes standard on the newer G37 intakes, was co-developed with K&N (should still flow well), and the oiled filters can cause problems with our MAFs if excess oil gets pulled up through the intake. It's a little tricky to install yourself (the main reason I wanted to be extra sure it would fit before ordering), but there are a lot of G35 forum posts showing how to do it by removing your driver side fender liner...allocate an hour to remove one wheel (the extra space is worth it), pull a few clips and metric #10 bolts and you'll be glad you did -- the car sounds better and accelerates noticeably smoother.Also, in case it helps anyone... I had the CAI installed around 2009 and replaced the filter in 2012. A number of years, but I don't drive much at all... some reported replacing it after 50k+ miles. In three years I only put ~20-30k on the car (work, grocery store, occasional road trip -- I really try to save the engine). Still, the oiled filter I replaced was (in my opinion) FILTHY! I'm hoping the dry-flow filter will "shake itself off" from bumps and other road vibration more than the oiled (like I read), but still think minimally cleaning the filter every 15-30k is a good goal for those obsessed with performance. Then again, I'm pretty OCD. :-)Go for it... You won't be sorry!

Great Product
I drive a Speed3 with a Corksport 3 inch short ram intake. Threw it right on, fit perfectly and didn’t bother any of my wiring. Car was sucking air just fine. Been on for a month or so, still no problems at all
