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 the head and going to a full fabricated intake. The Air-Boss 67 is not just 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 .270" of internal height while still allowing the use of the factory mounting hardware.We've all have seen the head gasket failures between cylinders 5, 6, and the coolant ports with the new 6.7L siamese cylinder design. The Air-Boss 67 Grid Heater Delete removes the restrictive factory grid heater and opens up the internal plenum area to the starving rear cylinders. Increasing airflow to the rear cylinders reduces EGT's and allow you to run even higher fueling levels!

Love this hat!
Size: One Size, Color: White
The American Cattle Bull spur hat is simple class. The white color is so trendy and chic, and the cattle horns with spurs on the ends look very cool. It is an adjustable hat to fit a wide range of head sizes, and it is a quality flat-brimmed cap. I prefer a more rounded bill, so I have bent it and molded it to be more traditional baseball shape.

Fits good feels cheap
Size: One Size, Color: White/Black/Tan
At first glance this feels like it was put together by cheaper materials. The fit is good but the packaging didn’t help. It came with the front crushed. Hopefully this will go back now that I have it out of the packaging but that we will see in the next day or so. It’s comfortable on your head. The style looks good and the colors make for a balanced look. Blends in well with various colors. Just not sure if the materials will make for a long lasting hat.

Nice white hat from American Cattle Co.
Size: One Size, Color: White
Good quality white hat- very giftable! This a very cool hat from the American Cattle Co. The nice white hat with a rope and longhorn keeps up with current hat trends, while also having a very classic "trucker" look. I even left the tag on (I never do that, but it looks like a cattle tag and I thought it was funny and works with the hat theme).

Nice flat bill hat
Size: One Size, Color: White
My husband says this is a comfortable hat. It was a little hard to shape up when it arrived, but overall the quality of the hat is nice. Nice and white and a mesh back to it. The design is a burnt orange color. Nice fit and adjustable in the back.
