Say goodbye to hard starts and restricted airflow with the Glacier Diesel Power Mega-Flo Grid Heater and Air-Boss 67 Plenum Package for your 2013–2023 Ram 6.7L Cummins.
When you’re dealing with frigid morning starts or chasing cooler EGTs and better throttle response, this setup has you covered with two heater options and the high-flow Air-Boss plenum upgrade in one streamlined package.
Choose from either the SD or HD heaters, both heaters are fully emissions-compatible and deliver class-leading heat output for consistent, reliable starts in any weather.
- Standard Duty Single Element heater, ideal for those in milder climates who need occasional cold-start support.
- Or go all-in with the Heavy Duty Dual Element version, perfect for extreme cold environments and northern climates where dependability is everything.
Paired with the Air-Boss 67 Grid Heater Delete, this package takes your intake airflow to the next level. If your EGTs are creeping too high or you're not getting the full benefit of your fueling upgrades, the Air-Boss 67 is the answer. It's not just a flat plate delete, it’s a billet aluminum, internally elevated plenum cover that’s precision machined to flow maximum air, especially to cylinders 4, 5, and 6 where airflow typically suffers. Glacier engineered this plenum to gain a full .220" of internal height, all while retaining the use of factory mounting hardware. The result? Significantly increased airflow, better fuel utilization, and cooler exhaust temps without major head work. Compatible with all stock-style intake manifolds, the Air-Boss 67 is the most effective grid heater delete upgrade available short of milling your intake plenum.
If you're after cold-start confidence, serious airflow gains, or both, this package delivers.

Worthy
Size: Small, Color: Calypso Blue
I have to say, I seldom receive something thru Amazon that's 100% worthy! I wear F P & AE & these look just like the model! I usually wear a M, but knowing how fp sizing is, I got the S. Fits perfect with even a bit of room. Im 5'3", 127lbs, 27 waist. Definitely great with flats, but I'm not sure yet with any other than tennis shoes. The paint splatter on mine are less than picture....no complaint here. They have a bit of stretch, I like real jeans, so I can live with it. They are soft & actually made well. Only downside to this order, Amazon made me purchased over what I wanted to, to get it by promise date, never happen & getting very common with that trick, not appreciated, so beware you may not get them on promise date

Way to short, cute, but short
Size: Medium, Color: Green Multi Combo
I would give these a 5 star but they were 3 inches to short. So cute though. Will try a large to see if that makes a difference. Im 5'7" 147lbs. Everything else was a great fit but serious highwaters
