WEB EXCLUSIVE: Glass-reinforced nylon 6 has been the material of choice for replacing metal in automotive air-intake manifolds. Now, for the first time, glass-filled polypropylene has beaten out nylon for this application in a wide variety of Volkswagen 2010 models. XMOD GB306SAF from Borealis in Vienna, Austria (U.S. office is Borealis Compounds LLC, Port Murray, N.J.) is a 35%-short-glass PP with an operating temperature between -40 C and +120 C (-40 F to 446 F). It was chosen for its cost and weight savings of 10% to 15% vs. nylon. It also offers better sound damping than previous plastic intake manifolds. The VW manifolds are injection molded by Mahle Filter Systems UK at the same speed as nylon manifolds.

In failure analysis, there is a tendency to gravitate to a few common test protocols. But this approach can result in a mismatch of techniques to the problem.
