Yet Another Header Question

[luke713]

ok...i know that this question is all over this forum...im looking into headers for my truck....2001 Silverado 1500 5.3L 2WD...after reading 10-15 of the already posted topics, i have decided on these:

 

Thorley Headers 310Y-DA

 

now, the question i have is, what is A.I.R. injection? and i see nothing on this page about these having the EGR connection. I believe my truck has the EGR, but not the AIR...so please fellas, help with your header knowledge just one more time...

WOW...no response...

AIR is air injector reactor and only if you have RPO "K19" and yes you have EGR.
