I just removed my universal conical filter and installed a Ractive heat shield filter. WOW. The car pulls much better especially down low, and it sounds meaner (although only I would notice that ). Definetly a worthwhile investment for Duratec guys who don't have homemade heat shields. Cost me $27.
