Those things are intended for CAI that move the intake WAY down low... like next to the road... so if you drop into a deep puddle and fully immerse your intake, it will sense the pressure change and kick in.

There is absolutly no value in adding this to the stock, JWT Pop, or K&N setups. If you fully immerse your intake, hydro lock is only one of MANY other problems your about to experience.

I also speak from experience. I bought one and was gonna try to make it work. Finally gave up and bought the K&N kit.

I have the 3"... I 'll send it to ya for $25 if your interested in experimenting.
Still interested in the JWT Pop? It's on ebay right now.
Lemme know.
