cold air intake

[Timthebrickman]

i saw on this forum somewhere that the silencer box can be removed for better air flow ,whats the best way to rework the duct workand rid the silencer box.and is this worth the time and effort

help us out a bit bud, what year truck, and is the engine bone stock? Since you said silencer box, I assume you have a 96+ vortec but you know what assuming does

You don't have to "rework" any intake tubing to get rid of the silencer box. All you have to do is take it off and get a rubber cap to put over the hole.

This is right...or you can be really ghetto and use the bottom of a coke can, it fits perfectly over the hole and then just secure it with the stock rubber peice and hose clamp

I actually used a grizz wintergreen lid and siliconed it in place and put the box back on. Looks stock but still same effect as removing the box

Since I owned both that is why I was wondering which one he was talking about. Maybe he will come back and give us more info so we can help him

But yes, as stated, you can just pull it off and cap it. If you like you can put it back on so it appears stock over the plug. You will see zero performance benefits from doing this.

There is no magic bullet for improving fuel economy, and realistically the more you do to the engine, the worse the economy will be until you get it re-tuned.
