My nismo intake fit fine, just had to bend the hole just a tad, nothing major. 

The problem I did have was the foam bypass valve... after about a year it ripped apart and I had to replace that piece with a silicone coupler

I actually still use my upper part as part of my intercooler piping.

you dont have to cut anything.  take a pair of vise grips to grab the metal and bend it down a bit to enlarge the hole.

wow....thanks for the quick responses


I am gonna get the Nismo CAI..... and while I'm at it a header/midpipe too.....I might as well do it all now....haha

Filter seems to be good... I had it on my car from 20k to 40k miles, never cleaned it and it's still fine

Can anyone tell me what generation this one is??....it looks different than the others I have seen

and the bypass valve looks to be made of rubber instead of foam...

looks like the gen2 i have

+1. Vise grips and 30 seconds of your time. I've done it on two specs.

The CAI is completely worth it, especially if it's one of your first mods. It will really awaken the spec, and you will love the sound from it.

thats a specv intake i have the same 1 lol

the one in the earlier post has 3 pipes. nismo intakes/any intakes never had 3 tubes. it was always 2 tubes + maf adapter. the one pictured way above also doesn't have a 3" to 2.75" reducer for the throttle body from the final pipe.

I asked for the part number and the seller gave me (16576-rnb55)........so I checked that on a bunch of other sites and thats what I need.....so we'll see

i just bought my nismo cai this week and it goes on tomorrow so im really excited, not a bad price though.

Buy a replacement filter too I have had mine for about 2-3 years and it started to dry rot so I had to buy a new filter. I ended up getting a Fujita which sits a lot higher up on the pipe than the Nismo one. Also I don't know if I am the onlt person but the hold where it mounts to the fender just ripped open. So I had to ghetto rig it till I can get it fixed nice and good. And you don't have to cut but, the directions say that you need to grind out the hole.

I got the complete nismo set up.....

intake
headers
exhaust
suspension kit (springs & Shocks)
sway bars
strut tower bar
bushing kit

they are all awesome parts and worth the investments.......

Check to make sure the adapter flange that connects the bypass valve to the MAF is the correct size.  I had a problem with mine and didn't know it.  The dealership installed it for me and forced it onto the bypass valve and cracked it.  A few years later without know it had fallen apart on the bottom side and was sucking in unfiltered air and fouled up my throttle body.  I had to order a new bypass valve and had a buddy that works at a machine shop mill me a new adapter plate.  It was made from a solid block of aircraft aluminum instead of a two pieces welded together.  We also kicked around the idea of making it from Nylon.  The stuff he has access to at work is used in high heat and extreme cold enviroments (also available in 5 colors).  The best part is it only took 2 days to make the part and it's pattern is now sotred on a disk for future production.

i was gonna get the nismo cai but then i got the injen instead and i like it no problems whats so ever.
