AEM air bypass valves create a vacuum leak to bypass the air filter in the event that the air filter sucks up water. Air bypass valves are typically installed onto the air intake tube on cold-air intake systems.

Product Reviews    Review part 20-403S

The AEM intake bypass valve arrived promptly and was a perfect replacement for the original equipment of a [brand] CAI.I am pleased with the product and would recommend it. However, I do think the price could be lowered to below $60 and that this would be reasonable for said product.

The process it took me from ordering to receiving was very quick and easy. The product came with all materials to install and installed easily with the included instructions. This has helped me with my water issue when driving in the rain with a cold air intake. Would recommend to anyone who has a cold air intake and drives daily in wet conditions.
