Ive heard people talk about them, but im unsure of what they are or how they work. Are they worth the money? what kind of hp increase could i expect?

 

btw, i did search, i just couldn't find what i was looking for.

 

i think they are worth it

 

They are a good mod, but completely removing the sleeves and actuators gives you a bigger top end gain, but it does take down low end power a little.

 

They are useless. We've had this discussion before. They're useless theoretically and do nothing on the flow bench. In addition, they create the potential for loose parts slamming around in the intake plenum and into the engine.

 

Better check this thread out first.
