There comes a time when one needs to realize what is needed and what is not. It their was really a need for extra oil filtration, don't you think Cummins or Dodge would have explored it, and add it if it were to prove usefully??
I love to add on to my Dodge like anyone else, but if you are just adding something to have something others don't, then it is not healthy to you or your engine. Diesel equipped trucks have shown a steady and constant rate of growth over the last ten years, some might call it a "Boom". There popularity and acceptance into the main stream of truck and SUV owners is a result of higher power ratings and increased fuel mileage figures. This has spawn a new and very profitable aftermarket segment, the diesel performance market. And as like anything else, money drives the market. Most people adorn their new trucks and SUV's with power enhancers, convenience accessories, and engine life enhancements like synthetic oils, better filters and increased maintenance awareness. Everyone wants their truck to be unique to them, a personal statement about the owner and his take on life in the truck world. In this quest for personal expression, many new and helpful products have been released, most have a use and place in the diesel truck market, making life better, faster, and easier then before. But some products make it to the market, by trying to "reinvent" what is their, Or by trying to make others believe there is a "need" that has not been meet. Luckily for us, 90% of all aftermarket pieces fill a void, they make life easier, replace week parts, provide more power, or allow us to monitor. The parts or pieces that fall into the 10% that do not live up to company claims or are not needed as their adds suggest are the ones we most talk about on these forums. They are after all the ones with little proof to back-up the companies claims. So they end up as subjects of interest, political hot spots where some defend their purchase like loyally party members. The post generally divide into two groups, the yes they work because I bought one , and the side that concludes it's a quack part only designed to take your money and run. These types of parts are always debated with great vigor and emotion, many times leading up to the interruption by a moderator. I must admit, I like reading them, often comparing them to the "Comics" because they are funny. Why do so many find that they have to defined the parts they buy? Shouldn't the company do that? Because I use a certain brand or type of part does not make me an instant expert, it only means I have experience with that part on my truck, in my region. I did not test every like part, on every truck and in every circumstance. No, I only tried that part on my truck in my neck of the woods. I am not a expert,... master diesel this or that..... just a fellow TDR member that tried a part of his truck.
The controversial parts that most often come to mind are the Tag, both TagI and TagII. The stock type of oil and air filters. The Vortex generating thing's that go on the back of trailers. Oils: brand,type and weights. External oil filters. After market turbos. Shocks. Tires and Hitches (including brake controllers) and performance injectors.
