Well right now Crawford is one of two aftermarket plenums that can handle boost. The other one would be SSR Engineering who developed and entire new plenum, not just the top half. Since both of them are made from metal as opposed to plastic like Kinetix, they are readily available to handle boost applications. I personally am waiting for the APS tall boy manifold to come out but it looks like it will be a few months before anyone has one in the states. Also there is Kinetix Racing who keeps on saying that they will have a metal intake manifold available, they developed a prototype over a year ago but it did not produce any HP and since then they went to plastic. Now they did say they would have the metal one available in December, but it seems like all they do is talk and don't produce anything. People have been waiting for it over a year and still there is nothing. Well thats all I can think of.

You don't even have to worry about the intake plenum imo. The OEM one is still good on the Performance Motorsport's 350Z, and it has over 1,000hp. The new Kinetix will be good for f/i. There are a few Kinetix V4 plenums being used with f/i. Altered Atmosphere may be making a full plenum soon that uses the oem engine cover.

I have Kinetix and love it but if your going F/I I would wait on the APS or Kinetix aluminum. Crawford is just too **** ugly along with their strut bar.

It's not an overly difficult install. There's some fidly bits with disconnecting and reconnecting the hoses near the firewall. The job took me about 3 hours working on my own.

TIP: The plenum can vibrate against your strut bat. I ended up placing 2 washers under each of the 8 bolts holding the strut bar in place to stop the vibration.

Thanks for the feedback buddy. Much appreciated :D
