What's your goal for "upgrading" the intake? Sound? Power? Other?
Honestly, most aftermarket intakes are a joke, do nothing to improve performance, and "less restrictive" means less filtration and more junk being inhaled into your engine. The only intake mod even remotely worth the money is the Air Raid MIT, and they don't make one for our trucks where you can buy just the tube. The cone air filter is worthless, and that's a lot of money for a plastic tube.
If you're looking to improve performance, a tune is going to get you the best bang for your buck. My Blackbear tune really woke up my Burb.
Other than that, more power is going to require heavier modifications - new cam, forced induction, etc.
