I’ve decided to buy a Ramair cone filter. Been looking at this for a while. I know some say the standard box is a decent design and works well. Honestly, I love the noise of an induction kit. So I’m tinkering with some aluminium I had lying around to try and make a heat shield to hopefully keep the hot stuff away from the filter. Has anyone else done this? If so, does it help? Below is my first attempt.
