your comments please for those who have first hand experience on this...

i read from another forum that such an air filter is only good whenever the engine bay is still cold, but performance derived from it drastically drops after an hour of driving, or when the engine bay becomes too hot...

my question is, when they say performance drops, do they mean it becomes worse than a stock filter?

please help me on this one... i plan to install one in my car...

thanks..
