I want to know the stock intake tubing size. I want a intake but not ready to spend 300$ on something that has no numbers or anything to offer besides looks and that swoosh sound. I am going to wait and see all offerings from every company and then I'll buy one. Meanwhile I want to fit a cone filter to the stock tubing. I know I'll have to fabricate something for the sensor in the stock air box but I am willing to do it. It should be less expensive and get the same sound. So, what is the stock tube size?
