6.7 Cummins EGT Relocation: Do You Need One? Buyer’s Guide
Author’s Note: I spent $78 on the wrong kits before figuring this out. Here’s the guide I wish someone had written for me.
Let me tell you about the day my truck went into limp mode on I-25.
I’d just finished a DPF delete on my 2018 Ram 2500. Pipe bolted up, tune loaded, everything torqued to spec. Fired it up - sounded incredible. Fifteen minutes into the test drive, the check engine light came on. Then the truck cut power. I limped home at 45 mph, fuming.
The code? P0544 - Exhaust Gas Temperature Sensor Circuit, Bank 1 Sensor 1.
I’d removed the DPF but didn’t relocate the EGT sensor the ECU was still looking for. The truck thought its exhaust was reading zero degrees, panicked, and shut me down.
That’s when I learned: a delete pipe is only half the job. EGT relocation is the other half - and skipping it is a guaranteed CEL.
What Is an EGT Relocation Kit, Actually?
An EGT (Exhaust Gas Temperature) relocation kit does exactly what it sounds like: it moves your factory temperature sensors from the DPF - which you just removed - to a new location where they can still read exhaust temperatures.
The kit typically includes:
- Probe adapter - allows the OEM sensor to thread into a standard 1/8" NPT bung
- Extension harness - extends the factory wiring to reach the new sensor location
- Weld-in bung (optional) - the threaded port you weld onto your new exhaust pipe
Without it, your ECU either throws codes (if the tune still monitors EGT) or you’re running blind on exhaust temps - which is dangerous if you tow heavy.
Do You Actually Need One? The 3 Scenarios
Scenario 1: Your Tune STILL Monitors EGT - YES, You Need It
Most tuners (EZ Lynk, EFI Live, MM3) allow you to keep EGT monitoring active even after a delete. Why would you want that? Because EGT is the single most important gauge when towing. If your exhaust temps spike past 1,300°F under load, you need to back off before you melt a piston.
If your tune keeps EGT active, you must relocate the sensors you’re keeping.
Scenario 2: Your Tune DISABLES All EGT - Maybe
Some aggressive off-road tunes disable all EGT monitoring to avoid codes entirely. If that’s your situation, you technically don’t need a relocation kit - but you also lose your most important engine safety gauge.
I don’t recommend this. Even a $50 EGT gauge is cheap insurance on a $15,000 engine.
Scenario 3: You’re Keeping the DPF - No
If you still have your factory exhaust with the DPF intact, your sensors are fine where they are. A relocation kit is for deleted trucks only.
The Real Cost of Getting It Wrong
| Mistake | Consequence | Fix Cost |
|---|---|---|
| Buying M12 kit for M14x1.5 sensors | Adapter won’t thread | Another $40-80 |
| No extension harness | Splicing 4-5 wires under the truck | Time + frustration |
| Cheap bung, bad weld | Exhaust leak, false EGT readings | Re-weld at exhaust shop |
| Not protecting harness | Melted wires, short to ground | New harness + tow bill |
| Not confirming with tuner | Relocating sensor ECU ignores | Wasted afternoon |
The TruckTok kit avoids all of these. M14x1.5 adapter (correct for 2013+), plug-and-play harness (no splicing), stainless bung option, and high-temp loom included.
TruckTok vs The Competition: Honest Comparison
I’ve now used or handled kits from four different brands. Here’s how they actually compare - not from spec sheets, but from turning wrenches.
| Feature | TruckTok | BD Diesel | Flo-Pro | Amazon Generic |
|---|---|---|---|---|
| Price | $39-$110 | $85-$130 | $45-$90 | $20-$40 |
| Thread (2013+) | M14x1.5 ✅ | M14x1.5 ✅ | M12 ❌ | M12 ❌ |
| Harness | Plug-and-play ✅ | Plug-and-play ✅ | Solder req’d | Solder req’d |
| Bung included | Optional | Yes | No | No |
| Heat protection | Loom included | Loom included | None | None |
| Install time | ~45 min | ~45 min | ~2 hrs | ~2 hrs |
| Warranty | Yes | Yes | Limited | None |
TruckTok ($39-$110)
Best for: 2013+ Ram owners who want the right thread pitch without paying BD prices.
The standout feature is the M14x1.5 adapter at a sub-$50 entry point. Most budget kits only come with M12 - fine for 2007-2012 trucks, useless for 2013+. The harness is genuinely plug-and-play with OEM-style connectors, and the optional weld-in bung is CNC-machined 304 stainless, not cast pot metal.
Two variants: harness-only ($39.99) if your delete pipe already has a bung, or the full kit with bung ($109.99) if you need to weld one in.
BD Diesel ($85-$130)
Best for: Someone who wants a name they’ve heard of and doesn’t mind paying more.
BD Diesel has been around forever and their kit is solid. M14x1.5 adapter, quality harness, good instructions. But you’re paying ~2x the TruckTok price for effectively the same components. If brand recognition matters to you, BD is fine. If value matters, there’s no functional difference.
Flo-Pro ($45-$90)
Best for: 2007-2012 trucks only. Skip for 2013+.
Flo-Pro makes decent delete pipes, but their EGT relocation kits use M12 adapters and require you to solder the extension harness yourself. For a pre-2013 truck where M12 is correct, these are okay with some electrical skill. For 2013+, the thread pitch is wrong - you’ll thread it halfway and strip.
Amazon/Ebay Generics ($20-$40)
Best for: Absolutely nothing on a 2013+ Ram.
These are the kits that come in unbranded plastic bags. M12 threads (wrong), no harness loom (fire risk), and adapters that look like they were machined by someone who just learned what a lathe is. I’ve seen the threads gall halfway in because the machining tolerances were off.
The only scenario where these make sense: you have a 2007-2012 truck, you’re comfortable soldering automotive wiring, and you genuinely can’t afford $39. Even then, the savings aren’t worth the headache.
Why the Thread Pitch Matters So Much
This deserves its own section because it’s the #1 question we get: “Will this fit my truck?”
The 6.7 Cummins had a sensor thread change in 2013:
- 2007-2012: EGT sensors use M12x1.25 - this is what 90% of universal kits are made for
- 2013-2024: EGT sensors use M14x1.5 - bigger, coarser thread
Ram changed the sensor supplier in 2013, and with it came a different thread spec. If you try to thread an M12 adapter onto an M14 sensor (or vice versa), it won’t even start. If you somehow force it, you’ll destroy the sensor threads - and a new OEM EGT sensor costs $80-150.
Bottom line: If you have a 2013+, buy a kit that explicitly says M14x1.5. Both TruckTok and BD Diesel do. Flo-Pro and the generics don’t.
Weld-In vs No-Weld: Which Version Should You Get?
Most delete pipes come with at least one pre-threaded 1/8" NPT bung - but not all do, and sometimes it’s in the wrong spot for your sensor.
| Your Situation | Get |
|---|---|
| Your delete pipe has a bung in a good location | Harness-only kit ($39.99) |
| Your delete pipe has no bung, or it’s in a bad spot | Full kit with weld-in bung ($109.99) |
| You’re not sure | Full kit - the bung is $70 solo, but only $60 in the bundle |
The full kit bung is 304 stainless with a pre-machined sealing face. If you’re having a shop weld it, they’ll appreciate that it’s not the cheap cast-iron bungs that spit and spatter under a TIG torch.
Install TL;DR
Full step-by-step install guide is here →. But here’s the 60-second version:
- Disconnect battery - safety first
- Remove EGT sensor from DPF - 7/8" wrench, penetrating oil helps
- Weld bung (if needed) - or use existing port on your delete pipe
- Thread adapter into bung - with anti-seize
- Thread sensor into adapter - hand-tight + 1/4 turn
- Connect harness - plug and play, no cutting
- Secure & test - zip ties, heat shield, start the truck
Total time: 30-90 minutes depending on whether you need to weld.
What Our Customers Are Saying
“I bought a generic EGT bung kit first and it was M12 - would not fit the 2013 Ram sensors. The 2013+ 6.7 Cummins uses M14x1.5 EGT sensors and this TruckTok kit has the correct thread pitch. The bungs are CNC-machined and the weld-in plugs for the unused ports are included. If you have a 2013 specifically, do not buy a universal kit - get this one.”

Final Verdict: Which Kit Should You Buy?
| You Drive… | Buy… | Because… |
|---|---|---|
| 2013+ Ram 6.7 | TruckTok full kit | M14x1.5 threads, plug-and-play, best value |
| 2007-2012 Ram 6.7 | TruckTok or Flo-Pro | M12 is correct for these years |
| 2013+ and on a budget | TruckTok harness-only | $39 if your pipe already has a bung |
| Any year, want the brand name | BD Diesel | Good kit, just costs more |
For the vast majority of 2013+ owners, the TruckTok kit at $39 (harness) or $110 (full) is the right call. It’s the correct thread pitch, it’s plug-and-play, and it doesn’t charge you extra for a logo.
FAQ
I have a 2018 Ram 2500. Will this kit fit?
Yes. All 2013-2024 Ram 2500/3500 6.7 Cummins use the same M14x1.5 EGT sensor threads. Your 2018 is covered.
What’s the difference between the $39 and $110 version?
The $39 harness-only version is for trucks with a delete pipe that already has a threaded 1/8" NPT bung. The $110 full kit includes a CNC-machined 304 stainless bung for welding into a pipe that doesn’t have one.
Will my truck throw codes after installing this?
Only if something is wrong. Common causes: connector not fully seated, harness touching the exhaust and melting, or your tune disabled the sensor you just relocated. Double-check the tune configuration first.
Can I install this myself or do I need a shop?
If your pipe already has a bung, it’s a 45-minute driveway job with basic hand tools. If you need the bung welded, you’ll need a welder or $20-40 at an exhaust shop. Either way, you don’t need a full diesel shop.
Does this work with EZ Lynk / EFI Live / MM3 tunes?
Yes. The kit is hardware only - it doesn’t interact with your tuner. As long as your tune keeps EGT monitoring active (most do), the relocated sensor will read normally.
Why does my 2013+ truck need M14x1.5 instead of M12?
Ram changed EGT sensor suppliers in 2013, and the new sensors have larger, coarser threads. An M12 adapter simply won’t thread on. TruckTok and BD Diesel kits come with M14x1.5 - most generics don’t.
My Amazon kit came with M12 threads. Can I make it work?
No. Forcing an M12 adapter onto an M14 sensor will destroy the threads - and a replacement OEM sensor costs $80-150. Return the Amazon kit and get one with the correct thread pitch.
Do I need to relocate ALL my EGT sensors?
No. Only the sensors you told your tuner to keep monitoring. Typically that’s just EGT 2 (post-turbo). EGT 3 and EGT 4 are inside or after the DPF and get coded out.
