THE AEM DIESEL & PETROL WATER/METHANOL INJECTION SYSTEM ADVANTAGE
Water/methanol injection (WMI) systems reduce air inlet temps and enhance combustion efficiency on turbo Diesel applications, which allows an engine to deliver more power with less effort. Water/methanol injection also offers a host of benefits that promote engine longevity, including the reduction of carbon deposits left by a Diesel’s exhaust gas recirculation (EGR) system. AEM’s Water/Methanol Injection Systems for turbo Diesel trucks and SUVs utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol injection system.

Water/Methanol for Diesels & Petrol of all Boost Levels
AEM Electronics offers two different water/methanol controller designs for HD and Diesel trucks:

One is a Boost Dependent HD Controller and has an on-board MAP sensor (up to 40 PSI) with a molded in nipple for a boost hose pickup (PN 30-3301 with 5 gallon tank, PN 30-3303 tank-less).

The second HD controller features a multiple input design. The Multi-Input controller can be programmed to work with a 0-5v signal from an external MAP sensor for Diesels running over 40 PSI of boost, or with a frequency based Injector Duty Cycle (IDC) signal, frequency-based mass airflow (MAF), or 0-5v voltage-based MAF signal (PN 30-3351 with 5 gallon tank, PN 30-3352 tank-less).

WATER/METHANOL INJECTION ADVANTAGES FOR ENGINES:

Reduces Air Inlet Charge Temps
Water/methanol’s “liquid intercooling” effect on turbo Diesel engines can reduce air charge temps by as much as 100 degrees, and deliver a more oxygen-rich air charge.

Enhances Combustion & Efficiency
In addition to cooling air inlet temps, as the water absorbs heat in the combustion chamber and converts to steam, the steam’s expansion rate increases the mean effective cylinder pressure without causing dangerous pressure spikes. This effective increase in cylinder pressure combined with methanol’s promotion of complete combustion allows your Diesel engine to burn fuel more completely. When fuel is being burned more completely less is wasted, which can increase fuel economy.

REDUCES EXHAUST GAS TEMPERATURES (EGTs)
Because Diesel vehicles using water/methanol injection burn fuel more completely, less un-burnt fuel is present in the exhaust manifold where it can flash ignite to increase EGTs and create particulate matter (soot). Water/methanol injection eliminates this secondary combustion of raw fuel in the exhaust manifold to reduce EGTs by up to 250 degrees, and reduces harmful particulates to extend engine life (and that expensive particulate filter).



Robust, Easy to Use Controllers
The new HD controller designs feature large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the HD controller housings for mating to the redesigned wiring harness’s positive-lock connector. The Boost Dependent HD controller housing (PN 30-3301 w/ 5 gallon tank, PN 30-3303 full kit without tank) has a molded-in, barbed nipple to accept a boost hose (up to 40 PSI) and a wiring legend on the back. The Multi-Input controller (PN 30-3351 w/ 5 gallon tank, PN 30-3352 full kit without tank) has an easy-to-remove plug covering the programming dipswitches and a programming legend on the back for the 0-5v and frequency based settings. Both controller housings feature an easy to access integrated fuse and molded mounting tabs.
 

Simplified Wiring
The wiring harnesses for AEM’s Water/Methanol Injection kits are terminated with a positive-lock connector on one end and have color-coded wires to ease installation. Both the power and ground wires for the pump are included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.
 

Integrated Boost Safe Feature
The controllers for AEM’s Water Methanol systems include an integrated “Boost Safe” output feature that monitors the entire injection system and triggers a ground signal via an output if it detects a voltage-related error (short, bad connection, broken wire, overheated pump, high or low voltage signal, etc.), allowing users to define their failsafe strategy from something as simple as flashing a warning light to more advanced strategies like pulling boost or ignition, or switching fuel maps on a standalone engine management system. Combined with the integral and highly accurate conductive low-fluid switch in the tank, “Boost Safe” can also put your engine in safe mode before the system runs dry. This exclusive feature is found only on AEM Water/Methanol Injection Systems.
 

Heavy-Duty High Pressure Injection Pump
AEM’s internally-bypassed water/methanol injection pump does not cycle on an off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery.
 

Low-Profile 5 Gallon Tank
AEM’s Diesel Water/Meth systems are available with or without a low-profile 5 gallon tank. The 5 Gallon tank includes a high-tech conductive low fluid level indicator with a positive lock connector and color matched wires to the wiring harness, and baffles to reduce fluid slosh.
 

Machined Billet Injectors and Nozzles
AEM includes two precision-machined billet injectors in its Diesel Water/Methanol Injection kits that feature an integral check valve to prevent unintended fluid flow. Three billet injector nozzles are included for matching water/methanol flow to an engine’s horsepower output (see chart below).
 

Revised Flow Control Strategy for More Linear Fluid Delivery
AEM’s engineers spent extensive time revamping the HD water/methanol controller’s flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine’s need for water/methanol injection, which further improves charge air cooling and reduces EGTs.

  • Boost Dependent and Multi-Input HD (external 0-5v MAP or MAF/frequency MAF) controller designs feature large adjustment knobs, integrated plug for harness connection, integrated fuse, covered status light and test button for enhanced splash resistance and mounting tabs

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.

Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside. The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath. But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package. These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!

These hold up very well
Color: White, Size: Standard (Pack of 2)
I have NO luck with pillows. I’ve been in stores & tried them. They seemed ok there. At home, nope. I’ve been getting headaches & neck aches from lousy pillows. I’ll change one, a few nights relief. It doesn’t help that I’m prone to headaches. After reading about different pillows, I settled on these. The reviews were better than so many different ones I was looking at. Including high priced & brand names. I bought the standard size. When I saw, “Customers Usually Keep This”, I kept my fingers crossed. When I received them, I took one out of the package & put my head on it & thought, oh no! This is too hard! I tried it again. Ok….. I slept on it & haven’t had any pains since. It’s soft but firm enough to keep my head from sinking & messing up my neck. I don’t move. No more flipping my pillow over. My head doesn’t go below my neck anymore! This has been 2 months now, but it hasn’t changed at all. I wake up happy, not complaining. No more pains or headaches. This saved me from losing days with a heating pad or an ice pack. The price was excellent for 2 pillows. I can’t believe a blind buy was the answer! These are incredible. Finally, something worked for me.
