Well made and high quality parts. It is pricey, but it only pulls cool air from outside the engine bay. I had another open type breather on the car prior to this. I have the ability to monitor my intake temp, and at idle using the Momentum intake it dropped 35 deg. F. Cold air means power--enough said.
Only thing that needs to be changed is the soft rubber on the filter that sits against the plastic housing should be reinforced does not always sit well allowing hot air to enter
