6.7 Cummins Grid Heater Delete Pros And Cons

Alright folks, let's talk about something spicy. Something that gets Cummins owners all riled up. Get ready, because we're diving into the world of the grid heater delete.

I know, I know. Some of you are already clutching your pearls. But hear me out! This isn't some evil plan to destroy your 6.7 Cummins.

The Alluring "Pros" Side

Breathing Easier (Maybe)

The main argument? Better airflow, baby! Supposedly, getting rid of that grid heater lets your engine inhale a little deeper. Think of it like taking off your restrictive tie after a Thanksgiving feast.

More air equals more power, right? Well, maybe. It's probably not going to turn your truck into a rocket ship.

But hey, every little bit counts, especially when you're chasing those elusive horsepower numbers.

Simplicity is Bliss

Fewer parts, fewer problems. That's the idea, anyway. Less electrical stuff to potentially fail down the road.

Who needs more wires and relays causing headaches? I certainly don't.

Plus, it just cleans up the engine bay a bit, doesn't it?

"It's a Race Truck, Duh!"

Okay, let's be real. For some, it's purely about performance. Strip it down, lighten it up, and squeeze every ounce of power possible!

If you're building a dedicated race truck, deleting the grid heater is almost a no-brainer. Almost.

Just promise me you're not driving it on the street. (Wink, wink.)

The Shadowy "Cons" Side

Cold Starts? Good Luck!

Here's the big one: cold starts. That grid heater is there for a reason, especially in colder climates.

Without it, starting your 6.7 Cummins on a frosty morning can be...challenging. Think of it as trying to convince a teenager to wake up for school.

Prepare for some serious cranking and maybe even some ether assistance. Not fun.

Warranty? Gone. Poof!

Messing with emissions-related equipment can void your warranty faster than you can say "catalytic converter."

Are you willing to risk that? That's a question only you can answer.

Consider the potential cost of repairs before you go snipping wires.

Is it Even Worth It?

Honestly, how much performance are you really gaining? For most daily drivers, it's probably negligible.

The slight increase in airflow might not outweigh the hassle of cold starts and potential warranty issues.

Think long and hard about whether the benefits justify the risks for your specific situation.

The "Save the Environment" Guilt Trip

Look, I'm not going to preach about emissions. But deleting your grid heater does affect how your engine runs during cold starts.

It might not be a huge impact, but it's something to consider if you're trying to be environmentally conscious.

Plus, you might get some dirty looks from the Prius crowd. Just sayin'.

My Unpopular Opinion

Here's the thing: for 90% of Cummins owners, the grid heater delete is probably unnecessary.

Unless you're building a dedicated race truck or living in a perpetually warm climate, the downsides likely outweigh the perceived benefits.

Just leave it alone! Save yourself the headache and keep your truck running reliably. You’ll thank me later.
