Well, I've always wanted one, and my Nismo filter was looking pretty beat up.
I tried to put it on just in place on my WAI, and no dice. The universal flange (75mm) made the filter about 2 inches too long. No way it was fitting. I went to pepboys for those modular piping things you can mix and match and connect.
What a waste.
Those suckers are so flimsy and brittle, i just put two pieces together and they started to crack.
Thank goodness for Big Al's. They do a lot of work for me down here, custom exhaust, lower tie bar, header, they don't mind doing custom stuff for me. So, I went there and asked, hey, can you cut off part of my WAI piping, right near the breather? They said sure. So they took two inches off from the end near the throttlebody, leaving about an inch and a half before the breather hole. I think I would have not had to remove so much, but I have that throttlebody spacer there as well, and it was just too tight.
As you can see from the pics, it was a close fit still, but after shifting the battery a smidge towards the front of the car, and towards the radiator, it JUST fit
Just for the record, everything that looks orange in the pic is actually red. It's a cameraphone, whaddaya expect?
Impressions so far? Throttle response is much smoother. WOT is actually noticeably louder, but normal driving sounds the same. I'll know in a few weeks if there's any affect in gas mileage, but i doubt it. Better growl under acceleration.
