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.

Great Toys for Chewers
Color: Purple
Love these dog toys, they are so well-made and keep my Golden Retriever busy for hours. The variety of sizes is nice too, they aren’t heavy at all, but they sure hold their shapes , even with the constant chewing. The price was very reasonable, too.

Great product
Color: Purple, Color: Purple
My dogs loved these toys. Durable and apparently very coveted as my puppers “argued” over who got each one. Kept them playing and chewing for hours. Giving only 4 stars instead because I Wish the size was bigger because I have found that sometimes I don’t see it and stepping on it is Absolutely NO FUN.

Rottweiler approved
Color: Purple
My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!
