good product for spares

Works very well, do tests by hooking up a vacuum and submerging the k&n filter in a container of water and the bypass kept the water flowing.

Pros
  • Absolute legend
Cons
  • Almost never

Good insurance for your engine.

Looks very nice, like all AEM products, not the easiest of installs as you have to remove the air intake and cut out the section to install the bypass valve. First make sure you install CAI to find the right place for it and also remove any shavings left over from pipe cutting unless all that crap gets into your engine and is bad for the engine. I don't know if it still works and I hope I don't have to test it, but it's good insurance just in case. I installed mine on an 03 Accord i4 with a 2"…

Pros
  • Dope 🔥
Cons
  • Nothing

Fragile to say the least

I purchased this product for my AEM cold air intake system to eliminate the possibility of a water seal, a condition that occurs when your engine ingests water that is not compressed like air can. resulting in engine damage. your piston rods.

However, I would like to share some tips to check before purchasing this product. First, this valve is large, about twice the size…

Pros
  • This is amazing
Cons
  • Some bugs
