I have seen a couple intake plenums discussed here. Any intelligent opinions as to which one is best, and any pros or cons? I seems like a pretty efficient bolt on enhancement for a NA application.

 

At the moment, there is only one, the Crawford.

 

has anyone thought about boring out the INSIDE of the stock plenum? i mean, yea its only a few more MM, but hey. a litte here.. a little there. add a small spacer gasket, but its no Crawford plenum, but an idea.

 

Cheston,

How about the Esprit Plenum (addon?)? It looks like a 'riser' for the stock plenum. $500 bucks tho...

 

Cheston, the great Technosquare research donor. Thanks for that effort. I want to stay NA, so I want the Tehnosqare ECU, True dual exhaust (HKS?), and an improved intake plenum. I hope this thread will lead me in the right direction. I have seen 2 available plenums, and 1 being developed. I want the biggest BANG for the buck.

 

Actually

lsdunique has a prototype
Top Secret has a production version.
Esprit has somewhat a plenum (spacer kit)

 

Haven't seen the Top Secret one, got a link?

The problem with the Esprit one is apparently they need to lower the entire engine so shorter engine mounts are required. Maybe the problem is with it clearing the brace so if you were happy to remove it then you may get away with it.

 

Hey guys dont forget Tommy Kaira. They have a plenum too!

 

who's that senator?
