Splitters, endplates, tire spats, hood vents, fender vents can all change airflow feeding into this part. Our testing was done on a car with our V3 aero kit, fender and hood vents. Your results may vary. \u003cbr\u003e\u003cbr\u003eOur serrated design is more effective than the small curved profiles you commonly see on Supra's, and Porsche's to combat this noise.
