By using a deep pleat design we were able to outflow K&N and create a filter that lasts longer while making more horsepower. We flowed our filter vs the most common K&N filter in each size and were able to beat K&N’s numbers every time.  The filter's outlet has an internal velocity stack to improve air flow into the intake tube.  Each filter is embossed with ZZP's logo on the end and includes a stainless worm drive clamp.  The below list shows the size and which intake each filter comes standard with.  They can be used in custom applications, just chose the correct filter for your application!

This particular Model is a Cone Style, 5" in length, with a 4 5/8" base, 4 1/4" top and 4" inlet (Most commonly used in ZZP's Fenderwell Intake)

This is a very compact size come air filter to fit in tight spots that utilizes 4" piping.
