Banks Monster-Ram Intake Manifold System with Plenum 13-18 Ram 6.7L Cummins PickupWhen it comes to increasing power and the overall efficiency of your 6. 7 Cummins engine, airflow is king. By increasing the density of cool, fresh air into your engine, you're able to better atomize the existing fuel being sent to the cylinders, netting a more efficient burn of the fuel, hence increasing power and fuel economy, while reducing EGT's (Exhaust Gas Temperatures).

When it comes to increasing power and the overall efficiency of your 6.7 Cummins engine, airflow is king. By increasing the density of cool, fresh air into your engine, you're able to better atomize the existing fuel being sent to the cylinders, netting a more efficient burn of the fuel, hence increasing power and fuel economy, while reducing EGT's (Exhaust Gas Temperatures). Now, with the 6.7's, that's no easy feat because not only do you have an EGR valve situated in the manifold, but also a very restrictive grid heater that is part of the intake plenum. But, in usual Banks Power fashion, they went to work making the most efficient intake manifold kit while retaining a grid heater for those in cool climates, meaning you're not sacrificing a thing!
NOTE: This does NOT fit Chassis Cab. Use BAN-42804-R if you have that model.
WHAT IT DOES:
The Monster-Ram improves airflow from the intercooler, flowing 936 cfm (71.5 lbs/min) with Banks’ High-Flow Heater and Billet Intake Plate compared to stock's 421 cfm (32.16 lbs/min). Monster-Ram raises boost without increasing backpressure at the turbine. The result is a more responsive, power-efficient engine that offers even more headroom than stock for higher horsepower applications.
THE COMPLETE SYSTEM:
Banks’ High-Flow Heater and Billet Intake Plate complete the perfect system. The High-Flow Heater allows for the removal of the restrictive stock heater grid plate. The new vertical coil-style heater provides the same functionality for cold starts as the stock grid heater but without obstructing airflow. Replacing the restrictive stock grid heater plate with the Banks High-Flow Intake Plate removes all obstructions and turbulence in the airflow path.
HOW IT WAS DESIGNED:
Utilizing the latest in CFD (computational fluid-dynamics), tested on the flow bench, the dyno, and on-road, Monster-Ram is a beast that only Banks could have unleashed. A direct-replacement aluminum casting, Monster-Ram is instant power, performance, and acceleration gratification. The factory inlet elbow is cramped and angular in order to accommodate the path of the stock number one fuel line. Banks Engineers designed a new number one fuel line, allowing the Monster-Ram to flow more air without obstruction.
EXPANDABLE:
With four 1/8” NPT ports, perfect for temperature and pressure sensors, as well as, an optional secondary heater, the sky's the limit for data acquisition and expandability.

made well
Size: 8-10, Color: Black 4 Pairs
These socks fit really well. Comfortable and the price is a breath of fresh air with other brands of toe socks getting crazy expensive. Just went for my evening run and they felt GREAT.

Comfy and Warm
Size: Women 6.5-7.5, Color: Raisin
I'm very happy with these Original Slipper Socks. I normally wear a 6 1/2, so got these in XS/6 1/2-7 1/2. They are a little long on my feet, but they'll do. I'd rather have them be a little long than a little short, and perfectly sized slippers seem almost impossible to find these days. These slipper socks have a nice, comfy wide toe box, and the cushioned sole is soft, warm, and comfy. The suede on the bottom of the sole make these quiet and very comfy to wear around the house. The wool sock uppers are not itchy, but as comfy as a pair of warm socks.

Perfect for cool weather ...
Size: 12.5-13.5 Women/10.5-11.5 Men, Color: Light Grey Ragg Wool
I see a lot of complaints about fit and outdoor use of these ... I mean, these are slipper socks for indoor use! These are not shoes! If you want to walk outside in the snow, put on shoes or boots and then go outside ...
I have two pair of these and they are great! I really like the real leather soles and foam insole, instead of the cheap plastic soles that are sold on most house shoes ... They were a little tight on my ankles when new, but they relaxed a bit and fit perfectly now.
These are perfect for letting the TV watch you, sauntering, meandering, posing, consuming hot beverages, midnight strolls through the house, napping and all sorts of other indoor inactivity ...
It has been a few years, and I must say, my Acorn's are still working strong. It is about 60 degrees inside, and I'm working in the garage on a cold concrete slab. The red stripes look especially special with my Adidas sweat pants.

Cozy but...
Size: Medium, Color: Light Grey Cotton Twist, Size: Medium, Color: Light Grey Cotton Twist
These slipper socks are nice but could be nicer. The sock portion does Not have a heel; they are tube socks with a footpad sewn on. This means there is a little tightness getting your foot past the turn and then you end up with a roll of sock over your upper foot. Once that is all made comfortable, you are good to go.
I wear mine indoors and out for short trips to the patio and backyard. The sole material looks to be durable enough to last more than one season with this type of use. The footbed itself has just the right amount of padding: not so much that the foot can slid to the side and not so thin you can feel the joints in a tile floor ;-)

Size down. Thin soles are cold.
Size: Small, Color: Light Grey Ragg Wool
The ragg wool is warm and they seem well made.
The foot sizing is very long. I'm a 7.5 to 8 always. The choice was 6-7 or 8-9. The 8-9 is more than 2 inches too long. I'm afraid they will cause a fall. Also know that the cushioning is not as pictured. It is only half the depth of the leather sides. When you stand on anything but carpets, you feel the cold floor. This is all due to the gravity on earth.
