    Default Options for stock air box mods?

    Haven't found any threads on modifying the stock airbox. My `burb is a weekend warrior for camping and hauling toys with the the 3000 mile road trip to Idaho planned for Christmas.

    I need this rig to be bullet proof but also offer decent performance. Normally, I'll get a new rig and start throwing performance upgrades at it to see what works.

    In the New Economy () I need to be very conservative. I've had decent luck taking the stock airbox and adding a K&N filter, along with adding more air holes and a small scoop to the hood to direct fresh air right to the airbox.

    I was just wondering if there is a standard trick to modifying the factory intake system?

    Any pesky silencers or anything hidden inside?

    I'm pretty comfortable fabricating stuff and enhancing the factory set-up, and I've even designed and built my own ram air system on my old `92 F250 with the 460 in it...

    I would definitely be interested in some intake mods, it has been in the back of my mind for a while and I have been debating on whether to buy a kit or make one for my 99 burb. I would rather save the money and make one.

    I've seen guys drill 1/2" holes in the airbox on the fender side and behind the headlight. Than added a stock replacment K&N filter. Seemed to work.
