When it comes to letting your engine and valve covers breathe, Spectre has you covered in style. Spectre offers a wide range of vent filter style push-in breathers to match the look you are going for under your hood. Our vent filter breathers have an air filter look and feel to them. Offered in the same red, blue, black and white filter colors as our air cleaners, either with an Extraflow style or closed chrome style top, you can now match your breather to your engine air cleaner. These products are legal in California only for racing vehicles which may never be used, registered, or licensed for use upon a highway. See spectreperformance.com for CARB status on each part for a specific vehicle.
