Found this on the G37 forums, Seem Injen has made a Kit out for the HR G37 motor. Hopefully they will come out with a Kit for the Sedan also! They Claim 14 More HP, and 14lbs Ft or Torque! Which I highly doubt just from an intkae Alone? But the Kit Looks pretty Nice. Check it out with Pics from the G37 at this Yr's SEMA Show in LV.

Oh they also show a Strut Tower Brace made by Circuit Sports! I really want this to come out soon!!

I've seen that thread, too. Although I'm not so sure if they can really pull 14 HP and 14TQ... I know they have the dyno sheet and all, but I just cannot believe that is possible just from the intake.... even if it's two. At least not until some other member post their Dyno before and after the Injen.

As for availbability, I've heard that Injen is planning to release a set for our cars in 1Q 08. AFIK, AEM, JWT, and Injen are all coming out around the same time. Along with the additional heat shield from Fujita. It's gonna be a busy quarter for us 2nd Gen G Sedan drivers.

PS. I don't think Injen has come out with the intake for G37 either... I think it was a prototype that was installed for the SEMA.

EDIT: There is a post about this from 350Z forum for their 07 350Z.

 

injen always claims high hp/tq gains by allowing the humidity/gas/heat to play a big role.

i had an injen CAI on my 02 specV and like it. eventually made it into a WAI after the thing almost had a hole wear into it from where it passed through the fender. soft motor mounts and a torquey 4 cylinder do not go hand in hand.

finally a had enough with boltons and n2o and went boost! lol

 

If they make it for us, it will be the ONE to get. The Injen CAI on my RSX-S was a legit horsepower maker.

 

The Injen intake in that picture from SEMA is not a CAI, it is a short ram. Why wait when Stillen and Fujita both have the same thing out now.

 

At least Fujita intakes don't come with heat shields... weather functional or not

I'm waiting on the JWT Pop-Charger. I've heard many good things about them from the previous gen coupe owners. I'm looking forward to the sound as well.
