Water Resistant: Filter cover Hydrophobic treatment helps repel moisture and protect against water entering the engine due to puddle splash or heavy rainstorms. Although our Pre-Filters are proven to be extremely effective in repelling water, please keep in mind they are NOT WATER PROOF. If submerged, your intake can hold or pass water. This treatment will last for six months to one year, depending on use and conditions. As a general guideline we recommend replacing your Outerwears air filter cover with every other air filter service to help maintain its intended performance benefits. A quick test can help determine if it is time to change your Pre-Filter. Simply take an ordinary clean spray bottle filled with water and gently spray the Pre-Filter. If water beads off the Pre-Filter, your water repellency is still working. If you see water enter through the Pre-Filter, it is time to purchase a new cover. - - Maintenance & Cleaning - Depending on driving conditions, service intervals may vary. We recommend making a visual inspection as often as you would normally service your vehicle. If your vehicle sees a lot of dirt track competition (pulling/dirt drags) or dirt road driving, we recommend viewing the Pre-Filter at least after every race or trip. If you see a significant amount of dirt, you should clean the Pre-Filter. If the only driving you experience is street, we recommend checking the Pre-Filter every 3,000-5,000 miles. Although your Pre-filter may not require a thorough cleaning, you may want to shake off excess dirt to maintain your optimum horsepower and fuel efficiency, then reinstall. Caked debris can be loosened by soaking this filter cover, after being removed from your main filter and vehicle, in a mild soapy water solution and then rinsed clean and allowed to dry before re-installation. Do not scrub or use aggressive cleaning chemicals as the pre-filter and hydrophobic treatment can become damaged resulting in reduced efficiency and premature failure.

Customer photo review of FSD 03-09 Dodge Cummins Billet Heat Exchanger

The billet heat exchanger looks great and is machined nicely. No worries about an internal failure allowing fluids to mix. It seems to be doing its job. It's more robust than the factory style cooler but I don’t believe it is quite as efficient based on warm up times I’m seeing. My only gripe is the bracket mounting bolts, they thread directly onto the cooler instead of passing all the way through and securing with nuts. Make sure to use thread locker along with the lock washers. As a rough guide, torque for M8 fasteners in aluminum should be 11-15 ft lbs, no torque spec is listed for the mounting hardware in the instructions.

Customer photo review of FSD 2003-2007 Dodge Cummins Heater Hose Kit Black Braided

It’s not bad, I was in a bind and needed a quick fix to get my truck back going. So first things first, the kit works. You can get rid of the steel lines and these will take their place. With about an hour and a half and a little research it doesn’t take much to get these hoses installed. However, I have some gripes about this kit. 1. You have to be very careful about how the lines are run to prevent the hose from kinking. 2. There are no p clamps or hardware included to hold the lines in place. To improve this kit, I’d toss some hose clamps, a couple bolts with some p clamps to hold the hose, maybe a couple pictures on where to run things too, or even total install instructions. Stiffer hose would be good too, in my pictures you can see that the hose going to the front of the engine is trying to kink as it makes the bend to run beside the turbo.

Customer photo review of Kingspeed Billet Front Cover 94-02

It came with no gaskets this item deff needs to be sold with cover gasket as well as the seal for the crank even a plug for the vent or a fitting to hook a tube to the vent. Didn’t come with shit but bolts. Now I got to track everything else down seperatly makes it a pain in the ass. At this point I’d rather have stayed stock

Customer photo review of FSD 2010-2012 Dodge Cummins Factory Replacement Transmission Line Kit Black Braided

I installed them when I built my transmission. Hoses are good quality but fittings felt kind of cheap. Not a bad kit at all. I’d recommend it to anyone. Substantial trans temp difference after putting them on. My trans runs a lot cooler now that I’ve bypassed the heat exchanger. 2012 ram 2500 with 68rfe. 9/10 would recommend. Just be gentle with the fittings

Customer photo review of FSD 03-09 Dodge Cummins Elite Drop-In Transmission Cooler Kit

I installed this cooler and a few weeks later got into a wreck that was able to damn near total my truck, the frame is bent in 4 places and it shifted my ranch and bumper a foot. This cooler was the only radiator that survived everything else was destroyed and wrapped around the cooler. I called customer support and was able to order new stainless steel brackets and this cooler will live again. I’m very impressed with the quality and strength of this part and would gladly buy it for another truck.

Customer photo review of Kingspeed 06-Current Dodge Ram Billet Budget Builder Valve Cover

I love the product. I am just upset that it wasn’t clear it doesn’t come with any hardware. I currently have no clue what barb fittings and hose sizes I need to get for the valve cover to my catch can. I am currently using a hardware store setup as this is my first Cummins and my first quality build of a truck. If there’s anyway you could assist me or point me in the right direction that would be awesome. Aside from that I’ve had nothing but compliments on it, I actually won top 10 truck and SCT x GFP in Nashville a few weeks back. Everyone including myself love the valve cover.
