i goignt o purchuse one of these within the next month and just wondering which way to go. and are they difficult to install. and what should i do about the draw straw thanks

 

There is little diiference between the two units. I would go with the air dog. The filters are cheaper. They both do the same thing! They are slow to install, I mean the first time doing one takes time. Once you do it, it is fairly easy. Just my thoughts!

 

Is the length on the drawstraw the same for all trucks (after cutting), or do you still have to find that out for yourself?
