Better protection...more air flow

Put this on my K&N filter and it allowed me to remove the airbox lid. Add the DynoJet stage 2 kit with the filter and outerwear and you got yourself a great combination!

Good Prefilter

A friend suggested i try one of these, because my quad was having some issues. Works great, and is easy to install. Helps keep my K&N filter drier and cleaner.

Would recommend

Does what it is supposed to do. Never had an issue.

Cleaner engine runs better!

I run these with K&N filters on all my rides, street and off road. And they work great! Filters last longer, and if in a place you can't clean the filter and it gets mucked up, remove the pre-filter for a clean filter underneath! Only downside is they claim the water resistant capabilities only last a year, so if true, these are a yearly replacement if they are in places they get wet.

Best thing for your playbike!

This is the best thing that you can do for your playbike. It will increase the life of your engine, and keep most of the really big particles out of your filter. It cleans really easy also. Must have.

if you give us a call we can assist with getting you a pre-filter for a specific size filter rather than having to order the pre-filter through our model fitment system.

this particular pre filter only fits the K&N filter that comes with the ProDesign and Modquad airflow systems. You only receive 1 prefilter for the desired ATV.
