I have an extra one. I don't know if it's the larger filter or the smaller filter but I know it's not the very first generation. I have an identical one in my car.
There was a time when I thought we were buying a friend of mine's SHO for my son, but that didn't happen. I put the cart before the horse and had ordered some parts. I don't come on here that often, but people around here do know me. PM me you're interested and I can send you some photos. I do like the M design on my car. I like the way it looks. I like the sound. I like that for no explainable reason, it reduces the amount of carbon that comes out of the exhaust pipes. And I very much like the fact that I can easily reach the transmission dipstick with it installed. Better than with the factory box. Better than with the K&N Typhoon I also had installed. Better than the Airaid I had installed.
Yep, I tried them all. I will tell you, I did not notice any performance gain or loss from any of them. But, I ended up staying with the M design the reasons stated above.
