Description

'07.5-'18 Mega-Flo S-3 6.7L Cummins Intake Manifold

The Mega-Flo 6.7L intake manifold is a precision, permanent mold, aluminum casting. Casting via permanent mold and heat treating gives the Mega-Flo S-3 superior material density for final machining. The permanent mold process offers a precision part with a great finish for colored powdercoat.

To lower restriction even further we have gone to a 5 bolt mounting design. This design eliminates the pass thru boss needed for the 6th bolt and allows us to open the cross sectional area even further. Some 5 bolt manifold designs allow "gasket creep" which causes long term gasket failure due to thermal cycling. To eliminate this, we leave a gasket retainer boss for the 6th bolt location during final machining. This boss captures the gasket and eliminates gasket creep.

For accessories such as boost gauges, water/meth or nitrous the Mega-Flo S-3 is ready. On the back we have added five 1/8" NPT ports which will cover all of your additions with room to grow down the road.

All Mega-Flo S-3 6.7L intake manifolds include mounting bolts, gaskets, plugs, and full color instruction manual.

*Note for Twin Pump Applications: Only compatible with Fleece or ATS twin CP-3 kits at this time.

I have a 2012 Ram 2500 Longhorn 4x4. This is my first diesel and at 5k miles I installed the Air-Boss 67 with The S-3 intake horn, CCV delete kit, 5 inch Flo-Pro turbo back exhaust, EGR cooler delete, H&S Mini maxx Race tuner and man my truck is ALIVE!!! I am absolutely shocked at how good it runs. The instructions were good and install was pretty straight forward. Richard called me back and emailed me and was on top of everything I asked! Top notch stuff and great people to deal with! My mpg has went from 13.8 around town to 18 and highway went from 16.5 to 23-25mpg depending on H&S tune I'm cruising on! Engine stays cooler it seems and takes a lil longer to warm up, because of the better flow! BUY THIS SET UP FOR YOUR TRUCK! No regrets!

Just installed this manifold and I highly recommend it. Not only does it come with very clear and precise instructions with take off of original and re install of the new one. It also leaves a very clean look under the hood. Throttle response is amazingly better and EGT's are a lot cooler highly recommended once again!!

Purchased intake 8-1-2011 and installed yesterday. Fit and finish was excellent, directions clear, concise, and kit was complete. Even included lock tight. I have a medium modified truck and was looking for improvement in intake flow etc. After installation, truck was obviously breathing better, spooled quicker, and the side benefit I wasn't expecting a slight increase in fuel mileage, maybe around a .5 mile increase. I attribute that to increased air flow to burn the heavy fuel mods on my truck. Great product recommend to all.

I recently installed this intake along with the "3.5 Boost tube on my 2008 6.7, and all I can say is AWESOME!!!! Fit and finish is excellent, I can't tell you how many times people have said " Damn that looks good " when I pop the hood. EGT's are down and the throttle response is a day and night difference around town, I HIGHLY recommend this intake to anyone!

They did it again! I recommend this product for anyone with a 6.7. It drastically reduced my egt temps and gave me an increase of 100 lb feet or torque on the dyno when paired with the Air-Boss 67. Awesome product worth every penny.

I have always heard this products was the absolute best, but what really got me was the customer service. It's rare when the customer service exceeds the product reputation now a days and Mr. Rich went above and beyond and not once did i feel pressured. He answered every single question in detail and did not give me short answers. He made sure i understand what his product was all about and made sure it was the perfect fit for what i needed. I will be coming back for everything else that i need for my truck. Thank you Mr. Rich for the outstanding customer service as well as an amazing product!

I highly recommend utilizing Glacier Diesel Power and i would not hesitate to put every single product that they manufacture on my trucks.

God Bless,
Clayton
