As a mechanic, I see if all the time. The increase in flow is more from the larger tubing than the filter element itself. You could do just as well using an oversized air box from another vehicle and adapting it to your own car. That is what I did on my cars/ I ran dual intakes with two air boxes using standard paper filters. I doubled my air intake capability but I have no oil to gunk up the wire on my MAF sensor. As for the guy using slick 50, Good Luck if you want 200K out of a motor using that stuff. We found out by accident in the 1980s that that stuff will kill you. We used it when it first came out and swore by it. One day we ran some in our race car which used cartridge oil filters instead of canister ones. We watched in horror as our oil pressure dropped slowly to nothing. Tore the motor apart and found nothing wrong. Looked at the filter and it was clogged with gunk. We then realized anything that can "seal" imperfections will also seal anything else. We took our normal oil filters off our cars and cut them open with can openers and looked at the elements. They too were clogged. The reason you dont notice it on a normal car is that regular filters have a spring loaded bypass so if the oil filter clogs, it releases to a bypass safety and oil just bypasses the filter element and goes on through. In other words, soon as you put slick 50 in your car or truck, the oil filter element clogs, the safety kicks in and from then on, your oil is no longer getting filtered but just going round and round carrying what ever gunk it picked up to he rest of the engine. I found a motto a long time ago that still stands in my mind, no additive is worth risking. if it worked, the main companies would add it to their product. Radiator sealer clogs your heating element so why not just fix the leak in your radiator right off instead of putting that junk in there. Mystery oil, slick 50 etc. Just fix your engine or change your oil as required. But then again, I am not one that bought into the internet bubble, the housing miracle or this latest rally either while many others did sooooooo Good Luck, Lee
