Looking at replacing my oem air intake. Is anyone using the granatelli dual cone, or halltech stinger?

 

Many here are using the haltech stinger, which is probably the best value for an air intake on the market. I have never heard of someone installing the granatelli. You may also want to look into the donaldson blackwing and vararam air intake. These are two other popular models.

 

Using the Stinger here and am quite happy with it

 

I use the stinger too, great value considering you get the bridge and everything. I don't have one complaint about the system...

 

I did allot of research and bought the Honker. It comes with everything you need.

 

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. $350-$400

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

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).

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

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 $239.00 or less, this system represents one of the best bangs for the buck. Fortunately, for about $40, you can add cold air induction. See my procedure at http://www.conceptualpolymer.com/corvette_c5_corner.htm

Halltech Stinger SSM – 2001-2004 C5 only (new!): 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.

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 normally hot underhood (and intake air) 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.

 

I just changed from the twin cone system to the Stinger (had to make room for the separator/catch-can that goes with the A&A evac pump). There was no measurable power difference between the two, and either one is an improvement over stock.

My chrome twin cone is for sale BTW. PM me if interested.

 

Thanks for the great summary!

Suggest you check out the Hurricane by Westcoast Corvettes before you make up your mind.

 

Same here. If you want cold air to it, just drill some one and half inch holes in your Fog Light Shroud.

 

I did the same as sxe60, except I removed the fog screens, cove vents and also removed the MAF screen. I just can't spend the money on the true system yet.
If the Z06 is doing the fog screen delete and modified air box, that is good enough for me.

 

 

If saving money is your thing...here.

Under $90 bucks you can't beat it. Works great on my Z06.

 

I've got the granatelli as a birthday gift and really like it. Opened up the fog light shroud to let cool air in. Works great. The filters are quite big and I personally like the look of dual cones as opposed to a single filter element. They are priced the same and I doubt there is any noticable performance difference.

 

both about the same........i have a new vara-ram in the box for sale, also a used haltech tric used that comes with the carbon fiber air bridge.

 

Hey, did you sell any of those yet??? If not email me at: viatality@hotmail.com

 

love my stinger...great value and worth the $$$

 

check this out before you buy something....interesting artical

it works really good!

 

Thats what I did, installed ZO6 screens and installed the Blackwing. Sounds great and runs great.

 

Great write up, SuperDave. You are amazing, good buddy!
