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!

Has Kojic acid and can be used daily without drying skin
One of my favorite products ever. I highly recommend this especially if you have dry skin. I find that using hyaluronic acid can sometimes make my skin even dryer and this has Kojic acid in it which gave me the ability to use it daily without drying my skin. It gives your skin a beautiful glow like you've put honey on your face. I absolutely love this product!

Get it!! You won't regret it
I don't know what to say but if you are considering buying this,do so... I've been using it a little bit over a week and to be honest I have used all kinds of makeup and lotions and I was never impressed even with experience brands,
This stuff I'm already noticing a difference in wrinkles and it's so soothing.
Just buy it and try it for yourself,
I'll definitely be buying more
