Hi, after going to Schucks and spending a little time with salesgal there trying to understand the K&N book, She went to the manager who pointed to aisle 3. There were universal cone filters (3-4"inlet)by Spectre sitting there for 25$--half price! Above, at the top was the valve cover filter for 5$ or so. So, I installed it with clearance problems from the pcv system and AC compressor. Anyway, it will work! Thanks, Roger
