What would you guys recommend for a 2006 5.9?

 

banks,afe,airraid,cfe are all good brands.

 

I've got the s&b and love it!

 

I used to be a big fan of AFE, recently I have been very impressed with S&B's product line up. Remember the #1 function of the intake . . . filtering the air, don't sacrifice filtration for flow! I've recently been very impressed at the fit & finish of the newest models of the S&B, and their pricing is very fair. Give them a look see, give me a holler if you need any help.

 

I would make a ******* whistler for about 1/3 the price of any of the mentioned intakes.

Also unless you are pulling 450+ hp....you don't need to upgrade the intake.

 

Good point! Most factory intake systems are good for 450-500hp depending on year/brand.

 

Love my AEM brute force. Polished tube looks good too. Sounds awesome
