Abstract: An induction system for an internal combustion engine, having a combustion chamber and an intake port in periodic communication with the combustion chamber, includes an intake tube having a lower trumpet (41) and an upper trumpet (42), each having an upper end, a lower end and a length; a transition section (43) extending between the upper end of the lower trumpet and the lower end of the upper trumpet; wherein the lower trumpet is connectable at its lower end to the intake port (22) of an engine and has an inner transition diameter (48) proximal its upper end, and wherein the upper trumpet has an inner expansion diameter (55) that is between about 68 percent and 217 percent greater than the transition diameter.

Abstract: A snap tight system including at least one fastening device is used for joining structural members to form an architectural assembly. The snap tight system includes a splice assembly having a first splice portion and a second splice portion. Further, the snap tight system includes a first structural member having one or more first openings, and a second structural member having one or more second openings. Further still, the snap tight system includes the at least one fastening device having a housing with a spring that actuates a first pin and a second pin. The fastening device joins the first structural member to the second structural member, such that the first pin extends through the first splice portion and the one or more first openings and, the second pin extends through the second splice portion and the one or more second openings so as to form the architectural assembly.
