TPI Runner Question

[timsiford at hushmail.com]

JW,

The Speed Density TPI plenums are very different from the MAF TPI plenums. 
 I have seen and worked with both. The SD plenums utilize only one special 
small diameter runner tube on the passenger side.  This is for EGR.  Idle 
air control is handled completely differently.  IAC air is injected through 
the front of the plenum via the Throttle body.  There is no longer any special 
plenum sections and runner sections for IAC.
