i hear a lot about that just install cone filter in evo X will have problem like lost boost,my question is what about other intake kit from AMS/ETS or...... ,do those have the same problem or no problem?i wanna get one ,any recommendation?

 

Not at all, an Intake leans out the factory tune and makes the car run quite a bit smoother. I can recommend ETS/AMS/Buscher, they all make a quality product.
