The folks at aFe did it again! by Mark Simonds
The New Hemi “High Breather” Filter.
Have you been putting off installing a cold air intake on your Hemi Ram because you didn’t want to give up the stock air resonator chamber? Can’t part with the “HEMI Magnum” on top of the engine? Have you been concerned about mud, snow, or high water getting into a low-hanging aftermarket air filter? Well, the folks at Advanced Flow Engineering listened to those concerns and came up with their newest cold air intake – the “High Breather”.
The aFe “Stage 2” High breather cold air intake is a marvel in engineering –and it looks fantastic under the hood. The massive high-flow intake filter sucks in cold outside air from high atop of the engine bay. The kit comes with a heavy duty heat shield to protect the filter from the heat produced from the exhaust manifold. The factory “accordion” style tubing is replaced by aFe’s smooth black tubing – less friction means higher flow of air into the throttle body.
Installation was a breeze (less than 15 minutes with simple hand tools). The instructions were one page and simple. The first thing with any modification under the hood was to disconnect the negative from the battery. Next was the removal of the factory air box and “accordion” style air tube. The final removal step is to separate the breather hose from the stock air box (the filter side). The aFe heat shield utilizes three of the four rubber grommets from the lower half of the factory air box – so don’t pitch the old parts too far! The aFe heat shield fits perfectly in the original plastic nipples that held the stock air box – only one bolt has to be removed from the upper fender area to secure the heat shield in place. The heat shield is more of a box than a shield… all possible heat sources are restricted with this system. The smooth, straight air tube fits right into the factory air resonator (stamped “HEMI Magnum’) with a rubber connector and two band clamps.
The next step is to attach the aFe high-flow filter to the other end of the air tube (inside the heat shield). I was amazed at how huge this filter was!! It was one of the biggest air filters I have ever seen – and here’s a big plus: it is an open-ended filter!! No top cap on this baby – air coming in from the passenger side grill goes right in through the top, as well as the sides. A very nice design indeed.
Another nice thing about the Stage 2 is that it has an aluminum cover over the heat shield box… not an open top that relies on the actual hood to seal the box like some air intakes on the market. The cover is stamped “aFe”, is secured with three screws, and looks great in contrast with the black heat shield box.
The breather hose fits on the nipple that jets out from the air tube – no cutting of the breather hose required. I also liked the idea that the air flow sensor stays right in the factory plug – didn’t have to mess with that pesky piece of plastic!
Once the cover was secured and the negative back on the battery, we strapped the truck on the dyno. We saw a 10.3 increase in rear wheel horsepower! Great looks, extra horsepower, and still have the “HEMI Hat” on top of the engine… what else could you ask for? More importantly, the piece of mind knowing you have an aFe cold air intake… dependable and capable - make this mod #1 in my book!
This is an example of how aFe responds to it's customers. We asked for more choices for Hemi cold air intakes and aFe delivered. The ability to adapt quickly and produce such quality pieces sets aFe above the crowd of filter companies.
