I want to swap my HX intake man. for an EX and I am told that I will loose my EGR system, what the heck is that?
Okay, Exhaust gas return system....why would a HX have it and a EX wouldn't?

It is the exhuast gas recirculation system. It routes exhuast gas back into the intake.....it reacts with some other bad chemical in the cylinder, to lower that type of emission.

I think it must have something to do with the Hx lean burn operation. Burning fuel as lean as an Hx does, creats more NOx I belive....so recirculating exhuast gas helps deal with that problem somehow.

 

how much of a difference did you notice with the EX intake and trottle body?

 

The EGR system lowers the peak combustion temperatures which reduces NOx's. EGR's are used mainly at part throttle. The system is off at idle(which would cause roughness if on) and full throttle(which would reduce full power if it was on).

 

are egr's on the other D engines?

 

Hmmm...don't know.

 

i'm pretty sure the HX is the only one with an EGR system

 

here is the final question, would it benefit perfomance wise to remove the EGR system?

 

I would assume it would help...especially at part throttle.

 

Probably would be a good thing to remove....but you won't be able to pass smog thats for sure.

Oh, I never did the manifold swap.
