Intake or drop in filter?

Skyz71 · April 16, 2006

Ok, couple of questions for y'all. First, would it improve gas milage, power, and sound if i removed the restrictive airbox cover of my 96' silv. 5.0 L with the OEM Air box. Stock filter, just a a little more air flow, just until i got an intake or drop in filter. And also, which would be more cost effective, Drop in performance filter, or full intake kit (preferably k&n or AEM brute force). Thanks

Take the lid off the air box. It uses a cylinder shaped filter. Even with the lid off, all air is still filtered. It sounds better and seemed to have improved the mpg about 1/2 -1 mpg.

For sure man, I went ahead and did that. It does sound better and I'll check on the milage. Thanks for the advice!

so its ok to take the cover off the air box and leave it off?

On the GMT 400 '96-'99 yes. The filter is still filtering all incoming air.

Ok, so now won't the air filter get dirtier quicker? I only drive around town and it's fairly clean around here.

I put a drop in K&N filter in my truck...no noticeable mpg increase, and with a 300hp motor I didn't notice any power increase. I think the only way to notice any kind of increase with these drop-ins is if you do it to an underpowered vehicle...I put one in my wifes Honda and noticed a slightly better throttle response and a little bit more pep in it's step.

Yeah the 5.0L is pretty under powered in my opinion. I'm a student on a part time salary, would it be more worth my while to get a drop in filter or keep on saving for the intake. And also, i'm goin for sound also on this one, woud the filter sound just as mean as the intake?
