Re: open element air intake on an EFI engine?
I have a K&N style on my Weber carb. Something you have to remember, your system can only flow so much air. On the Weber, the throat area is around 1.94 square inches. As long as no other part of the intake is smaller, adding an expensive filter will not add one thing. A fancy air filter cannot change the laws of physics. I have found in stock air boxes the heater control valve area is much less than 1.75 square inches, so I removed it and added a 2 inch piece of PVC that will go to a snorkel. Now nothing is less than the actual throat area of the carb. The same idea works for any car truck or whatever.
