What was the first modification you made to your late-model Corvette? If you said, "a cold-air intake," you're not alone. Cold-air intakes (CAI) offer a simple, affordable means of improving your Vette's output by increasing the amount of cool, dense air flowing into the engine. And unlike permanent changes to the motor itself, a CAI shouldn't affect your factory warranty, and it can easily be removed if you decide to sell the car.

While the principle of cold-air induction will work on any generation Corvette, the aftermarket has focused the majority of its attention on systems for the '97-'10 C5 and C6. (Owners of earlier-generation Vettes may elect to build custom CAIs to accomplish their goals.) Our official guide to Corvette CAIs will help you select the one best suited to your car-and your budget.

Because choosing a CAI is based upon a number of variables-such as engine type, current level of modification, planned mods, and appearance-we didn't favor one of these manufacturers over the others. Instead, we listed them all (half this month and half next month) and allowed them to state their case. All that's left is for you to decide is which one is right for your Corvette.

AFE - Advanced Flow Engineering
(951) 493-7155
www.afepower.com

Brief Description
aFe cold-air intakes are designed to maximize air volume and velocity and produce maximum horsepower and torque. Our C5 intake, for example, made 24 additional hp and 29 lb-ft of torque.

Trademark Features
All of our intakes include a huge air filter and a contoured, rotomolded plastic intake tube. They're available with our Pro 5R air filter for maximum airflow or our new Pro Dry S air filter for maximum convenience. All aFe products have complete engineering tests results including dyno and flow data.

Quote From Company
"aFe products are designed, tested, and manufactured in the USA by degreed engineers. Our goal is to design the highest-quality intakes and performance products on the market. We back up all of our products with real test results, but the real test is in the smile you will have from having installed an aFe product."

Airaid Filter Company
(800) 498-6951
www.airaid.com

Brief Description
Airaid intakes for the Corvette are new from front to back. Starting up front is our huge, premium air filter that flows more air than your car will ever need. Next is a computer-designed and flow-bench-tested inlet tube with a large oval inlet that keeps fresh air moving through to the throttle body with no restrictions. Perhaps the strongest and most unique feature of these new Corvette kits is Airaid's exclusive Cold Air Dam that is designed to keep more cold air flowing through to the filter.

Trademark Features
True bolt-on performance, no cutting or drilling required, no tuning required, lifetime "No-Hassle" warranty, and they're made in the USA.

Quote From Company
"For performance that is second to none, give your Corvette a shot of cold-air adrenaline using an Airaid cold-air intake system designed specifically for the Corvette LSX engines!"

Breathless Performance Products
(954) 925-7725
www.breathlessperformance.com

Brief Description
Our Vortex Rammer kit replaces the restrictive, stock airbox assembly on your Corvette with a revolutionary air cleaner containing an internal vortex velocity stack. It obtains cool, pressurized air from the radiator cavity through your modified shroud. Air is forced through a sealed box and directly injected into your intake, lowering manifold-air temperatures by almost 30 degrees F.

Trademark Features
Our power duct replaces the stock air bridge between the throttle body and the MAF and increases the airflow to the motor by more than 40 percent. It's a one-piece unit, unlike typical two-piece seamed units, which have a tendency to crack along the seam. Our new power tube supports the MAF sensor and is optimized to increase airflow while being computer friendly. Dyno testing has shown up to 36 additional hp and 38 lb-ft at the flywheel. All materials and products are made in the USA to a high-quality standard.

Quote From Company
"Proven on the track and tested on the dyno to be the world's most-powerful ram-induction system."

Callaway Cars, Inc.
(860) 434-9002
www.callawaycars.com

Brief Description
Honker Cold Air Induction Systems consistently exhibit very high mass-airflow rates with a minimum of turbulence, allowing a greater volume of inlet air for increased power. A key element to the product is its unidirectional air path. The absence of abrupt changes in air direction, as found in other designs, facilitates air movement. From the outer surface of the air-filter element to the throttle body, the inlet air has a short, direct path.

Trademark Features
* CAD-designed main-duct shape and smooth inner-surface finish are engineered to maximize laminar flow
* Filter base positions filter element in OEM-designed, high-pressure area to allow access to cooler, denser inlet air from outside the engine compartment
* Duct and couplers manufactured with OEM-grade polymers, which are unaffected by severe underhood temperatures, lubricants, and cleaners
* Large, low-restriction, reusable panel-filter element features Callaway-specific double-lip seal to ensure air-tight sealing
* Compatible with all OEM engine management sensors
* Premium-quality hardware is used throughout for extended durability

Quote From Company
"Honker Cold Air Systems are used as original equipment in Callaway Corvettes and Callaway C16s."

K&N Engineering, Inc.
(800) 858-3333
www.knfilters.com

Brief Description
K&N replaces the Corvette's original intake assembly-including the airbox, air filter, and intake tube-with an all-new intake design. Air is drawn through a large K&N High-Flow Air Filter that increases airflow and never needs to be replaced. As it passes the filter, air travels through a larger-diameter rotomolded polyethylene tube that is specifically shaped to drive a more laminar flow of air to the car's engine.

Trademark Features
Guaranteed horsepower, improved throttle response, can be installed in 90 minutes or less, K&N's Million Mile Limited Warranty

Quote From Company
"The K&N High-Flow Intake System increases horsepower by 11.1 hp at 4,700 rpm over the stock intake configuration (tested on a C5 Corvette)."

Granatelli Motor Sports (GMS)
(805) 486-6644
www.granatellimotorsports.com

Brief Description
GMS is the creator of the Dual Cone Cold Air Induction system for the C5. This system improves mileage and throttle response, adds 15-16 hp to your engine's output, and is a direct OEM replacement. Our Cold-Air Intake with Ram Air Box system for the C6, meanwhile, increases horsepower and torque by way of better breathing. It gives a great, throaty sound under hard acceleration, yet it's silent at cruise speeds.

Trademark Features
The C5 system includes a high-performance air bridge, two open-element washable filters, and all necessary hardware. The C6 system uses a high-flow flat-panel filter measuring 14x19 inches, with a pleat depth of 1.5 inches. Both systems work with factory ECM settings, meaning no custom tuning is needed. After installation, less throttle angle is needed to achieve the same speed, so mpg increases based upon driving habits. Each system installs in approximately 10-15 minutes using basic hand tools (no cutting or modifications required).

Quote From Company
"The Granatelli name has been associated with speed for more than 70 years. GMS spends countless hours performing engineering evaluations and precision testing to ensure its customers receive innovative products and advanced automotive solutions."

Halltech Systems, LLC
(262) 965-4300
www.halltechsystems.com

Brief Description
Our induction system comes with a black or red cross-linked, polyethylene/nylon 66, 102mm MAF housing as an integrated part of the intake bridge. The impact- and heat-resistant nylon is 30-percent glass impregnated for strength and durability where it counts. The Halltech Beehive Ram Air Shroud and hood seal offer cold-air retention for lower intake air temps while idling and a ram-air effect when moving. (Our testing indicated a 40-50-degree [F] cooler IAT at a one-minute idle with the Beehive in place.) Cutting the radiator shroud is necessary on the C6 LS3, but not on the Z06. Ram Air requires two additional ports in the radiator shroud.

Trademark Features
* ISO 5011-certified filter media
* 12 hp/9 lb-ft torque gain over stock without tuning or Beehive shroud
* 15 hp with Beehive, not including ram-air benefit
* 25-30hp gain with LSXR intake manifold
* Warranty safe
* No chance of hydrolock, since our system locates the filter in the stock location
* 102mm nylon 66 MAF housing matches the new LSXR intake manifold and Williams Performance 102mm throttle body

Quote From Company
"Halltech's Killer Beehive Ram Air Induction System Package is the ultimate ram-air induction system for the LS3/LS7."
