ok, im too lazy to change the whole intake system as i don't have full exhaust anyway. so put in an K%26amp;N filter into stock box on my last filter change.
now. today i was inspecting my filter to see how dirty it is, on the street and drove back home without the filter cover(too lazy to put it back on). and the car goes slightly more powerful and there is significant louder induction sound after 3500-4000 rpm.(a deep lower pitch sound kicks in, definately not VTEC coz it's B18b).
as u can see. with cover on the air for the engine goes down a pipe from the air box to where i show the red arrow is. which is the coolest area in engine bay.
so.. what is the real purpose of that air filter cover and to direct induction air with a downpipe? is it ok to use the car without the air filter cover? things im worry about is that the air that goes into the engine will be too hot?
please tell me what u think!Integra Air filter cover on or off?its to block out the hot air from the engine bay and use just the air coming from your fenderr, if you take the 10 seconds and put the cover back on you'll get a little better performance, because the way it is right now your letting hot air get in which anybody that knows anything about cars knows that heat is the enemy when your trying for performance, the added performance your getting is from the filter itself, not because you don't have the cover on, also the small HP increse your getting from the K%26amp;N isn't enough to where you'll feel, your just feeling the better acceleration since the fitler is high performance so its letting in more airIntegra Air filter cover on or off?I think you are now sucking in hot air from the engine bay instead of cooler air from in the fender. Your brain and butt dyno are just making you think there is more power but in reality, there is no way you can feel the tiny difference and once things warm up, you will hurt performance. If you just want the noise then go for it.
