    building your own intake is probably the smartest way anyways... why pay 300 dollars for a tube with a cone filter on it lol...

    Anyways, just mod your box man. Open it and buy a K&N.. Also you might want to change that plastic flex pipe with steel pipe from a muffler shop. Just tell em you need some pipe bent, they will be happy to make some easy money... Just bring the truck and they can get the measurements...

    Actually, eBay is the most cost effective way.
    Since 90% of intakes actually have no R&D behind them and do nothing more than replace that ugly OEM plastic piping with shiny metal, the $40 intake will do the same job as a $300 one.
    eBay intakes can be had in around the $40 mark which includes a filter and shipping as well. The way i figure, $20 alone is the cost of a cone filter and my time, shipping, and materials are certainly woth an additional $20.
    Home made can be a big no-no. By using PVC or exhaust piping, you can actually damage your motor due to 'heat sync'. Both these materials are HUGE conductors of heat which defeats any purpose of a 'cold air intake' in the first place. Sure, it will look better than the OEM air box, but, it wont be good for your truck. And like i said, in materials from Home Depot to build one, plus a filter (and dont forget your time too!) your prolly gonna be close to the $40 mark anyhow.
    Hope this helps!

    $40 eBay intakes are normally just a 90* bend and a filter right off the motor. Not going to be any better or worse than a homemade hack job. If you go the homemade route it is going to need some sort of heat treatment/shielding to make it effective and worth it.

    The ones i see on ebay are metal too... Most cold air intakes are metal too.. Although you do have a point, if he got some heat shielding from summit he would be even more better off than plastic.

    True, but, they are made from aluminum which is not as big of a heat conductor as exhaust shop steel is...

    There is also full cold air intakes on eBay too that are more than just a 90 degree bend (aka, short ram intake). Heres a fine example:

    I know this is pretaining to the 1st gens in a 2nd gen area but, are the intakes from ebay any good that are for the 92' CPI engines? I have been thinking about getting one that has a long chrome plated tube that locates the Cone style filter in the area of the stock box. Wouldn't the chrome be a conductor of heat and make this even worse than running the stock box? Also, a true CAI in theory is one that runs down to the bumper to pull cold air from outside of the engine bay, not the air within it am I correct? Also, my factory intake has a hose with a bung for the air temp sensor, will one from eBay have one? Just wanted to know all of this before I go out spending money on something that may not even work.... -Josh

    -they are polished aluminum (for a chrome look), not actually chrome plated
    -your CAI theory is mostly correct yes! I havent taken apart my envoy intake piping, but, i know that on most cars (hondas, sunfires, etc), that even though the filter of the intake is located within the engine bay, there is usually a second set of factory plumbing from behind the fender or bumper leading into the bay and stops at the cone filter (or, where the OEM air filter box is) acting like a true CAI.
    -if the intake is intended for you vehicle, it will have a bung
