Easy to order and delivery as expected.
The air filter fitted well to the air box. Good upgrade for cheap price. I will be pairing it with velocity stacks soon.
Another high quality air filter from DNA! Superior molding to K&N and the most filter surface area you can squeeze into the stock airbox. It’s a super easy upgrade with no downside. Go for it!
The DNA air filter has way better air flow than the stock filter while keeping your intake tract system squeaky clean!
