Induction

The BMP/ProMini Induction (featuring an aFe filter element) was the first modification I had done to the Mini. Despite everything else I've done since, this intake was unquestionably the biggest "bang for the buck" modification. Real "seat o' the pants" improvement for a mere $200, not to mention the roar from the engine above 4k RPM... even with the stock header and exhaust!!! The one thing that bothered me is that the factory air box had a clip that held the fuel injection module. In removing the factory box, the module just sort of dangled in the engine bay. I knew the K&N Typhoon Induction for the Mini came with a bracket that held the loose module. I tried numerous times to contact K&N regarding buying the parts that made up the bracket. No dice. Some time later when I had a few bucks to spare, I bought the K&N intake... just for the bracket. When time came to clean the aFe filter (on the BMP/ProMini), I just decided to try out the K&N since the BMP/ProMini would be out anyway. Performance is essentially the same between the two units. However, the one thing I really liked about the design of the BMP/ProMini was the fact that it still made use of the factory cold air inlet. The K&N is really a HAI (hot air intake), although it is located fairly near to where the factory cold air inlet tube ends. The BMP/ProMini actually has a housing around the filter element & connects directly to the factory cold air inlet. After I did the MTH (Motoren-Technik-Hoelzl) Engine Control Unit modification, I thought it best that the little Mini engine be getting as cold air as possible (cold air = dense air = more air) to take full advantage of potential engine power.
