would it help or can i remove the stock lid on the air box of my 2006 power stroke to improve performance

 

Do you have a aftermarket intake? There is no airbox lid on the stock intake on a powerstroke.

 

the stock air cleaner has a lid in it held on with clips just curious if removing it would help performance by increasing air flow

 

Thats not a lid. That center section held to the two end caps with clips is the actual filter.

Edit - Heres a picture of the filter.http://k-mansparts.com/images/FA-1746.jpg

 

Leave it alone....it flows plenty of air just like it is.

 

well thank you this is my first diesel and half the people tell me to replace my intake the other half tell me to stay with the stock setup i had not looked under what i thought was the lid obviously.... i assumed and thats what i get so what should i do

 

Unless you are planning on 500+ hp, the stock air filter flows more than enough, it is an efficient filter also.

 

I still have my stock filter in place and have no plans of installing a aftermarket filter.

The only reason I would install a aftermarket filter is because it is alot easier to service the filter.

 

IMO as a tech with a lightly modded truck and access to lots of "stuffs" from time to time. I run a stock air filter.

 

I would have to argue with you on the part about easier to service the filter. It only takes about 2 minutes to change the factory air filter. The AM filters are a PIA and show not much benefit until a LOT higher RPM range.

 

I have to disagree Tim. It takes me about 7 minutes. Of course that includes 1 beer.

 

We agree to disagree then haha. It takes me about 5 minutes to change my air filter...mind you I have only changed it once so maybe next time I can do it in 2 minutes.

But my buddy has a AFE intake on his 6.0...takes maybe 10 seconds to unscrew the two thumbscrews and remove the lid....then another 10 seconds to loosen the hose clamp and remove the air filter.
