Questions for the covette gurus
1. What is the best cold air intake for my 2002 z06
2.What is the best shot throw shifter for my vette.
Any help would be great.

RE: Questions for the covette gurus
1. Keep in mind that 02-04 Z06s typically require a dyno-tune after the installation of an aftermarket intake system. The main culprit is their screenless MAF sensor, which allows turbulent air to pass by the heated sensor elements. Adding a larger intake filter increases this turbulent flow, which contributes to the resulting lean flow codes. That being said, here's more intake info:
If you live in California, think twice about the Vararam, as it can be a royal pain to install/uninstall/reinstall for smog tests. If you live in a state that doesn't have visual inspections, then take a look at the following (grouped by cold air and non-cold air, but in no particular order) and my comments, if any:
Vararam: Brings cold air in through the fog light panel area to a panel-type filter. Owners have had good luck with system on the dragstrip, but plan on spending hours to install and a bit more to get everything lined up well. Downside: Eliminates engine bay-cooling air that would've come in from the fog light panels (Z06 or coupe/vert with opened-up panels), so the engine bay may end up being toastier, especially if you add headers later. $300-$400 (NOT smog legal in CA)
Vortech Rammer: Brings cold air up from in front of the radiator and into an enclosed box. Its filter is quite a bit smaller than the Halltech Warhead or Blackwing unit. $250 (NOT smog legal in CA)
Callaway Honker intake system: This one relocates the MAF so that it is just in front of the throttlebody. It directs cold air from underneath and costs about $500. I believe this unit is 50 states legal (smogwise) for non=Z06 C5s. Excellent design and quality. If cost is no object, this bad boy should be at the top of your list.
K&N FIPK: This is more of a semi-cold air system, as the cold air intake opening is more of a slit. Its filter endcaps are carbon fiber. However, it is configured similarly to the Halltech Stinger-R and is 50-states legal. $350
Reverse Zip-tie: Allows cold air to be drawn in from underneath, but the bare filter is exposed to potential damage from larger objects. The advantage here is that you may pass smog if the tech doesn't know "which way is up".
Warm air systems: (Easy installation)
Halltech Stinger-R: Not only contains the massive Warhead filter, but also includes a larger-than-stock airbridge and smooth throttlebody coupler. For $350.00 or less, this system represents one of the best bangs for the buck. Fortunately, if you don't like Z06 screens in front of cored-out fog light panels, (for about $40) you can add cold air induction. See my procedure at http://www.conceptualpolymer.com/corvette_c5_corner.htm
This is what I did and a swap to smog-legal status is very easy to do, as I have kept my Z06 intake box.
Halltech Stinger SSM: This intake system features an even larger filter than that of the Stinger-R, TRAP, and Blackwing. < $400
Blackwing: Includes just a large filter, but an excellent one at that. Its cost is close to that of the Stinger. Like the Stinger, it is not smog-legal in CA, but can easily be swapped.
Volant Twin Cone: This system gives you more open filter surface area than any stock box does and is well suited to an engine bay that gets cold air in from the fog light panels, as the filters are more or less in the air flow path. $265
2002+ Z06 airbox cover: A larger opening allows more air to be drawn in through the filter. Expect up to a 5 RWHP gain from this simple swap. $50
Zip-tie: An easy and inexpensive mod (eliminates the OEM box’s upper lid), but its sealing ability is questionable at best.
How good are they? My experience has shown that most will bump up RWHP by at least 10. The advantage of having cold air is that power will not be "dialed down" under slow moving/stop&go conditions.
You could easily lose 10 HP with a warm air system after engine bay temps rise during slow-moving conditions. Cold air prevents this from happening.
2. Shifters
Medium effort, good vibration isolation and medium-length shifts:
C6 Z06 shifter
MTI (latest design)
Calloway C5 shifter (new)
Shortest throw but high effortand no vibration isolation :
Hurst
BPP (angled version is 16-way adjustable)
Ripper
