Why remove the heater grid?
Considering 'deleting the heater grid.
Question: What does it do anyway? Is it kinda like a gall bladder or 1-kidney...it does "something" but you can live with out it?
Question: If I remove/replace it, will I get any thrown codes? Will I notice any performance difference?
Location: South Texas. Yes, it does get cold here... 2-3 days a year...

I removed mine when I installed a 2nd generation intake horn to slightly increase air flow. I don't know if the grid heater is restrictive, but where I live it isn't needed. The only negative is that if the ignition is left on without the engine running it will throw a code, which is easily reset. I haven't noticed any oblivious performance gains. Cummins grid heater delete spacer #3922484 or 5266557.

Danalex:
The heater grid on our Dodge CTD Pickups are there to warm the intake air in cold temperatures so it is easier for the truck to start. It does the same thing as a glowlpug on the diesel V-8's in the Chevy's and Fords.
I don't have one in my 1996 Dodge CTD 12 valve either. I removed it a long time ago to get more air into the engine for performance as it is a restriction.
John is right on what he told you about the codes.
BTW,.....thanks for your service Sir! I also served in the Air Force during the Vietnam Years. I was a 46250 (Weapons Mechanic) but only stayed in for four years.
Take care.

Thanks guys! ((and thank you Sir John for your srvc!))
1) I'll probably just leave the grid heater there and will go for a better intake horn (CMF+ or Glacier). would rather not deal with the codes...
2) If I do remove the grid (i'm still tempted), I will just install an electric plug for those one or two chilly nights in S.Texas.

The intake horn I used did nothing for performance.
It did lighten my wallet.
EFI Live will yield a cleaner,smoother and more powerful engine.
I used Anarchy and the optional 5 position switch is very helpful. Even the 30 hp tune is huge improvement over stock.
Great guys with super customer service.
Ditto for the Airaid we both have. No seat of the pants effect.
