grid heat delete
#3
These Cummins engines dont have glow plugs to aid cold starts. The grid heater will heat the incoming air to ease cold starts. The grid heater delete will eliminate the grid heater and allows about half a pound psi of additional boost, at higher RPMS. Unless you have mucho mucho horsepower, and youre looking for every ounce of additional boost, removing it is futile. It does not really restrict airflow during normal everyday driving or towing. There is some info online regarding airflow testing with and without the grid heater. The difference is really insignificant. Check it out for yourself and you be the judge. I still run mine, as do many others.
