by-pass valve decrease HP?

I was wondering does installing a by-pass valve in a Cold Air Intake to prevent hydrolocking cause a loss in horsepower?? or anything to do performance wise??


thanks

The bypass valve may cause a slight loss in power due to the interrupted wall section created by the internal shape of the valve. In dyno testing we have found that the power loss is minimal. The bypass valve offers great security against hydro locking the engine in rainy conditions. If maximum power is the requirement, we suggest that the bypass valve be used in the rainy season and when racing use a coupler hose to make a smooth section where the bypass valve goes.

I think the bypass valves work on the 2nd generation AEM CAI only.. not the older AEM one..

yeah... they cannot work with First Gen AEM Intake because of the way it is bent.

2nd Gen AEM Inake is made for the bypass valve option...

the picture [below] from the celicastore looks like the one i bought but it says second generation for the description. i don't understand. the piping looks like its bent the same way since the others look more like straight pipes.

it only takes one time... and it could just be that single intersection during rush-hour traffic in the rain - where you had come to a stop and now need to accelerate out of spineyes

In SoCal - we get 'rivers' after every rain here tongue

I got my bypass valve for only 20 dollars from a friend who got the wrong size. I would have to say it is the least expensive insurance i have ever bought. Highly Recommended!!!
