GDP Air-Boss 67 Grid Heater Delete 07.5-23 Dodge 6.7L Cummins Cab and ChassisThe Air Boss 67 C&C is the first and only grid heater delete made for the C&C applications! EGT's running too high? Can't use all of the fuel you have available? The 6. 7L Air Boss 67 Grid Heater Delete gives the largest flow increase possible short of milling the cast plenum off of the head.

The Air-Boss 67 C&C is the first and only grid heater delete made for the C&C applications! EGT's running too high? Can't use all of the fuel you have available? The 6.7L Air-Boss 67 Grid Heater Delete gives the largest flow increase possible short of milling the cast plenum off of the head.The Air-Boss 67 is not just a replacement flat plate. The Air-Boss 67 Grid Heater Delete is a billet aluminum, internally elevated plenum cover designed to flow as much air as possible to cylinders 4, 5, and 6. With careful machining GDP was able to gain a full .220" of internal height while still allowing the use of the factory mounting hardware.
The factory grid heater used on the 6.7L trucks is the worst design yet for airflow. Not only is the flow area much smaller than needed, but the heater actually extends down inside of the plenum. This not only causes turbulence but reduces the needed turning radius area by 40%. The Air-Boss 67 Grid Heater Delete removes the restrictive factory grid heater and opens up the turning radius and internal plenum area to the starving rear cylinders.
Air-Boss 67 elevated intake plenums are compatible with all stock style intake manifolds and most aftermarket units that use stock thickness mounting flanges. The increased airflow provided by the Air-Boss 67 reduces EGT's and allow you to run even higher fueling levels!
For cold weather applications that still require a grid heater please see the new GDP "Arctic Heat" High Flow 6.7L Grid Heater Relocation Kit. When combined with the Air-Boss 67 you have the highest flowing cold weather package available on the market.

Looks nice but not comfortable
Size: 9.5, Color: Black
Look nice, fit well, but there is no cushion on the sole so feet hurt after wearing for even a short time.

Nice shoes
Size: 11, Color: Black
bought for my husband to wear to a funeral. Since he would only be wearing them for a day as we don't dress up ever he didn't want to spend allot. The shoes themselves look more expensive than they were and he said that they were comfortable enough. Not sure how well they will last with daily wear. the services had allot of dirt and the shoes were easy to wipe clean with a damp towel

From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.
