I was curious if it was ok to keep the stock airbox cover off? dose it hurt the car at all? thanx in advance!

 

the lost if any at all is very miniscule.

 

so dose it help or anything because it sounds very good.

 

some people dyno show gains some do not, but i do agree it does sound good. the only downsideof leaving the cover off is it exposes the filter and in turn will get dirty faster.

 

Yes, it negatively effects performance. You will now pull in even more hot air from the engine compartment. The design isn't great, but in stock form that little extension on the airbox tries to pull air from in front of the radiator. With the top off, air is drawn from the motor.

Hot air = not so good.

Butt Dyno = kick-ass sound!!!

 

Lid off=minus 5h.p.
If it's the sound you want,mod.your airbox.
You will get same sound,and you will get +/-3 more H.P.for free,with the lid on.

 

Where the hell did you get that info? That is the stupidest thing I've heard in a while.

Bottom line.....you will without a doubt lose 6-20 HP depending on conditions. That's a fact.

It does sound very cool though.

Get a nice intake...you'll get the sound and keep the power, maybe even pick up 2-5 hp...

 

I love your plugs !!!

 

Where do people come up with stuff like this?
(Maybe he's talking about the airbox lid from a Yugo?)

 

This is a repeating topic here, and there are some things I still don't understand. I DO understand that taking the airbox cover off will allow significant super-heated air from the back of the radiator to enter through the filter into the throttle body, thereby causing heat soak and robbing power. The power loss will be greatest when it is hot outside, and less (and perhaps zero) it it is very cold.

BUT, many commercially available CAI units also place a basically bare filter element in areas that appear dangerously close to the radiator "blast". The K&N "Filtercharger" is basically a stock configuration with the whole airbox removed. Some of these units place the filter element off to a side or low in the engine bay. Yet, I've attached thermometers in these areas and gotten readings up to 140 degrees on summer days.

So it would seem that taking the top of the stock airbox is bad, but so are many CAI units. Right?

Thanks,
