Excellent replacement for PRL Short Ram Intake
This K&N filter is the perfect size to replace the filter that comes with your PRL short ram intake. Everything bolted up exactly as the PRL filter and the K&N filter looks better than the PRL one in my opinion. Great filter, very happy.

Bad flange design
Does not fasten to pipe, when you tighten the clamp the filter slides off. Bad design
