You can make your own ‘Pro’ by buying a regular T800 and $3 worth of dampers.
If you can put a petrol pump into your gas filler valve on your car, then you can install a damper on the T800. All it takes is basic hand eye coordination.
@Slater do u know how long the normal Knowles filter can last? I heard it is easy to install but is it a pain to remove?
