It's been a quest to find someone local with a nice Gen 1 Cummins to get some photos for an instruction manual. When you live outside of a major city it can be challenging to find the trucks to work on. I finally was able to get my hands on a Gen 1 after our recent move to the Las Cruces New Mexico area when a nearby customer ordered their new Icebox Intake. Dylan was happy to help.
After working with Dylan we discovered a few modifications that we could make in order to make it easier to install the air filter. Let's face it there Amsoil and S&B filters that we have designed our intakes around are just HUGE! And that means it can be tricky to get them to fit in the space. We have sent our modifications to our manufacturer and should have the first new re-designed Gen 1's in stock by the first week in December....just so you know.
Okay now here is some exciting feedback from Dylan. This was my first email from Dylan but he had just taken a trip a few days earlier and had checked his mileage so be sure to read the reply below this one too.
I meant to write you during my lunch yesterday, but ended up taking a gear oil bath at work instead haha. So far, I'm very pleased! The sound is incredible. I feel like I'm in a little Kenworth, and any time I'm in a tunnel or riding next to a flat faced building, I can't help but get on it a little bit with the windows down.
The throttle response has also improved significantly. The previous owner had tweaked the injection pump a little bit, and I don't know the specifics of what they did. As a result, I always had a fair amount of smoke just off idle when I was starting off from a stop. With the new intake, a lot of that extra fuel I was dumping through the tail pipe has plenty of air to mix with now, and I've gone from a dark soot cloud to a moderate haze. I'm excited to really get the pump dialed in now that I have the intake side opened up.
I'm getting ready to head to El Paso, so like I said, I'll try to get you as close of a comparison as possible for the mileage between the before and after install trips. I'll also think of any notes I might be able to add as far as install tips go.
Thanks! It was a pleasure meeting you and being able to help you out. If there's anything else I can do, just let me know! Oh, and I won't forget to get you a good comparison between the Amsoil and the S&B dry filter!
After Dylan took the same exact trip that he had taken a few days earlier this was his email to me.
As promised, I wanted to give you an update on how the Icebox affected my fuel economy. In a word, phenomenal.
About the truck, for reference: 1992 Dodge W350, inter-cooled Cummins turbo diesel, Getrag G360 5-speed manual, single cab, 4WD, dually. The only existing modifications I'm aware of are a slightly tweaked injection pump and a 4" FloPro turbo-back exhaust with muffler.
On the 26th of August, I fueled up at the Valero in Alamogordo, and drove directly to El Paso. I used the cruise control as much as possible, and typically set it to 3-4 MPH above the speed limit. I then refueled at the Valero near Cielo Vista mall in El Paso. The purpose of this trip was to drop my girlfriend off at the airport, so there was a very small amount (< 5 miles) of in-town driving mixed in. It took 5.686 miles to fill the tank, after driving 73.2 miles per my tripmeter. I've calculated over several trips, comparing my tripmeter reading to my GPS calculation, that in order to obtain a correct distance traveled, I must multiply my tripmeter reading by 1.2. This puts the total distance for the trip at 87.84 miles. Divided by the number of gallons, this yields an average fuel economy of 15.45 miles per gallon. This was the trip that inspired me to look at air intake options, and eventually led me to your product.
On the 29th of August, after we installed the Icebox, I needed to return to El Paso. Again, I fueled up at the same Valero in Alamogordo, and drove directly to El Paso. As before, I used the cruise control as much as possible, and typically set it to 3-4 MPH above the speed limit. I did everything in my power to recreate the driving conditions from the previous trip. The purpose of this trip was a visit to the Apple Store in Cielo Vista mall to have a service performed on my phone. As such, I did not go to the airport, and did not see the small amount of in-town driving as before. The only other differences for this trip were that I had one less passenger along for the ride, and I left a bit less than an hour earlier (receipts show my refuel time for the first trip at 10:00 AM, and for the second at 9:11 AM). I refueled at the same Valero near Cielo Vista mall in El Paso, and it took 4.671 gallons to fill the tank. My tripmeter read 73.3 miles. After correction, this puts my trip length at 87.96 miles. Divided by the number of gallons, this yields an average fuel economy of 18.83 miles per gallon.
In summary, with nothing more than the addition of an Icebox to replace a (admittedly dirty) factory air box and paper filter, my fuel mileage increased a whopping 21.9 percent, from 15.45 MPG to 18.83 MPG. I used over a full gallon of fuel (1.015 gallons) less on a roughly 90 mile trip!
Again, I tried to make this as scientific and accurate as possible. There were slight variations between the two drives, but I think it's fairly reasonable to say that the Icebox did an excellent job of improving my fuel mileage.
Thank you for marketing such a great product! Let me know if I can help you out with anything else!
You can quickly improve your 1st gen cummins performance by replacing your factory air filter box with our Icebox Inkake for the 1st Generation Dodge Cummins. There aren'tmany options available in the marketplace for the older Dodge Cummins especially for the first generation diesels. Here is a photo of our Intake for the 1st Gen Cummins.
We recently received some photos from a customer that had just installed his first gen intake. Here is a photo of his Gen 1 Icebox Intake installed.
We have been using and recommending Amsoil's Nanofiber EA alr filters really right from the beginning. In fact our Icebox Intakes were originally designed and built using the Amsoil air filters. You could almost say that we reverse engineered our Icebox Intakes starting first with the Amsoil filters and building our intakes around them.
Our 8 ply cotton oiled and dry disposable filters are manufactured by S&B air filters, who also incidentally manufactures the Amsoil Ea filters for Amsoil using their Donaldson filter media. Here is some information about the Nanofiber Technology that you might find interesting.
What is Nanofiber Technology?
Nanofiber is a phrase that generally refers to a fiber with a diameter less than one micron. Cellulose fibers, on the other hand, are larger than nano- fibers and have larger spaces between the fibers, causing contaminants to load in the depth of the media and plug the airflow path, resulting in higher restriction and less capacity. AMSOIL Ea Air Filters incorporate a specially constructed cellulose media with synthetic nanofibers applied to the surface. Dust and submicron particles are trapped on the nanofiber surface, preventing them from lodging in the filter media depth.
We also highly recommend the Pre-Filter covers to use with your Amsoil filter. Here is a photo of the Amsoil EaAU4510 with the EaPF20 prefilter installed.
I went online to see if I could find a video that would share about the Amsoil Nanofiber air filters and I found a video by SyntheticWarehouse.com that does a really good job of sharing about them.....as I was listening to it they even mentioned Icebox...Awesome...Thanks SyntheticWarehouse we appreciate that mention! Here is that video for your viewing pleasure....
While we offer Amsoil air filters many of our customers will either purchase their filter from their local Amsoil dealer if they are not also Amsoil dealers themselves. And that is perfectly fine with us and why we offer our Icebox Intakes with or without an air filter.
We are proud to have the Amsoil filters available for our Icebox Cold Air Intakes as we think they give you a high level of performance. Order an Amsoil Nanofiber Air Filter and Pre-Filter Cover for your new Icebox Intake today!
A recent customer ordered one of our Icebox Gen 4 Intakes for his 2010-2011 Dodge Cummins and in a rush to get his cold air intake ready for UPS I had forgotten to include the installation instructions. So I emailed them to Jeff and he replied
"I didn't even need them! I am not the most mechanical guy in the world but your product was very straight forward and was a very easy install. The box looks great too. Thanks for the quality product. Jeff M., satisfied customer"
Thanks Jeff and thanks for the photo of your Gen 4 Intake Installed.
