The AirDog I-4G is the latest in fuel delivery for your GM 6.6L Duramax! Its patented design has been quality engineered to remove entrained air and water vapor from diesel fuel. The result is a compact, long lasting, efficient, and quiet fuel system made with superior quality.

AirDog I-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the fuel pump.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog I-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.

Unsure of whether you need the Airdog 100 or the Airdog 150? - Put it this way...if your truck is stock, or moderately stock(up to 500hp) you want the 100. If you've added a 100hp programmer or larger(500hp+), you will want the 150. If you have any questions, give us a call

Moisturized heels out of the box
Color: Fuzzy Lilac Purple, Size: Regular
Work without adding anything to your feet, but there are extra nice if you wanted to add a moisturizer to you heel and not get it all over your socks. Worth the money!

A Staple in Skin Care Routine
Style: Milky Toner
This toner has become a staple in my skincare routine. I have sensitive skin and a lot of products tend to cause irritation or redness, but this one has been incredibly gentle from the start. My skin always feels soft, calm, and hydrated after using it. The texture is lightweight with an almost soapy feel at first, but it absorbs quickly and never leaves my skin feeling greasy or heavy. It layers well with the rest of my skincare and works great both morning and night. I also appreciate that it gives results similar to more expensive brands without the high price tag. Definitely one of the better affordable skincare products I’ve tried.

My Favorite Product in the Milky Line
Style: Milky Toner, Style: Milky Toner
This toner has easily become my favorite product from Thayers brand and all other brands. I’m very picky about my skincare routine, especially when it comes to products I use daily, and this one has completely earned a permanent spot in my routine. It feels incredibly gentle, hydrating, and soothing on the skin without feeling sticky or heavy. I love the ingredients, especially the snow mushroom and hyaluronic acid, because my skin always feels soft, balanced, and refreshed after using it. I’ve also noticed my pores looking smoother and overall healthier since incorporating this toner consistently. The formula works beautifully with the rest of the Milky line, and my skin genuinely looks and feels better when I use it regularly. I’ll absolutely continue repurchasing this product.

Hydration + glow without irritation!
Style: Milky Toner
I’ve been using this milky toner for a couple months now and it has quickly become a staple in my routine. The texture is lightweight but creamy, which makes it feel more nourishing than a typical watery toner. It absorbs really well into my skin without leaving and sticky or greasy residue. I haven’t noticed that my skin feels softer and more hydrated after applying it AND it layers so nicely with serums and moisturizers. One thing I really appreciate is how gentle it is on my skin. It doesn’t cause any irritation, redness or breakouts! I actually feel like it helps calm my skin on days when It feels a little dry or “stressed”. Overall, I think it is a great option if you are looking for a hydrating, soothing toner that fits easily into either a simple or more detailed skincare routine. I will 100% be repurchasing when I run out of my current bottle

This will make your face soft and glowy!
Style: Milky Toner
This is GOOD STUFF! First cleanse face, then I tried using both a cotton ball and a cotton round, but in the end, I put a small amount right on my fingers and massage into my face. It seems pretty wet at first, so I let it air dry for a minute before adding my moisturizer. My face really seems smooth and even has a glow to it, which is unbelievable to me! My face also feels very soft and hydrated (and usually has some dry patches).
