Part 2: Manufacturers L-Z
Last Month, we brought you the first part of our official guide to Corvette cold-air intake (CAI) kits. In this issue, we're back with even more bolt-on induction systems that promise to boost the output of your Vette's engine without blowing a hole in 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 systems over the others. Instead, we listed them all and allowed each manufacturer to state its case. All that's left is for you to decide is which one is right for your Corvette.
Lingenfelter Performance Engineering
Brief Description: Our high-flow air intake system for C5 and C6 Corvettes features an inlet air filter that provides reduced inlet restriction, compared with stock and competitive units. This reduction is achieved by utilizing more filter surface area than any of the other leading air-intake systems and by using a radiused inlet entry built into the outlet of the filter itself. Our system is also designed to provide lower-temperature air from outside the engine compartment to produce optimal performance and consistency. The high-flow air intake maintains a high-quality factory appearance and includes a washable air-filter assembly, filter housing, fasteners, and detailed installation instructions. Systems are available for LS1, LS6, LS2, and LS7-equipped Corvettes.
Trademark Features: Flow-bench, engine-dynamometer, and chassis-dynamometer designed and tested; chassis-dynamometer-proven horsepower gains; same air-intake systems used on Lingenfelter engine-package-equipped vehicles; true cold-air design picks up air from outside the engine compartment; high-quality factory appearance.
Quote from Company: "High-performance air-intake systems designed to provide increased power, from the name in Corvette performance products-Lingenfelter Performance Engineering."

They have the confidence they're getting a great product at a good price from a company with 35 years of experience-and the finest people in the Corvette aftermarket looking out for them.
Quote from Company: "When we install cold-air intakes on our own Corvettes, we use our own products, because they're easy to install, they require no modifications, and, best of all, they produce power."
Brief Description: Our performance intake kits are all about improving your Corvette's engine, while still protecting it. We publish the ISO 5011 test results, so you can be assured that you're getting the airflow your Vette needs without sacrificing filtration capability.
Trademark Features: Quicker acceleration; reduced turbo lag (where applicable); more power; custom airbox for cool, dense air; improved fuel economy; lower exhaust-gas temperatures and air resistance; guaranteed engine protection; tested to ISO 5011 filtration standards.
Quote from Company: "We actually manufacture our products. Our competitors are more expensive because they have to purchase some or all of their components from other companies, which drives up the price."
SLP Performance Parts
Brief Description: SLP's cold-air induction system for TPI-equipped C4 Corvettes is constructed of the same materials as the factory unit. It uses a reusable filter and provides gains of up to 20 hp. Our C4 LT1/LT4/ZR1 CAI kit-known as "The Claw" for its unique three-finger design-is made from stainless steel and black powdercoated.
SLP C5 LS1/LS6 CAI kits, meanwhile, utilize our exclusive Blackwing filter, for gains of up to 23 hp. Our C6 LS2/LS3/LS7 CAI kits also utilize the Blackwing filter, along with an all-new air bridge, to produce gains of up to 15 hp.
Both C5 and C6 systems use a wire-reinforced, reusable-and-washable filter material, along with an exclusive airflow indicator that changes color when cleaning is required. Each system secures at the factory mounting points and comes with all necessary hardware and detailed installation instructions.
Trademark Features: OEM-quality construction and appearance; designed to fit and seal properly; airflow and filtering properties superior to factory system; withstands underhood temperatures; improved airflow through a more-efficient design; easy, bolt-on installation; reusable and washable Blackwing filters in each kit; supplied necessary hardware and detailed installation instructions; limited lifetime warranty.
Quote from Company: "Each SLP underhood cold-air induction package replaces the restrictive, power-robbing factory assembly. By picking up cool, dense outside air, these systems are proven to add additional horsepower on all applications and meet or exceed OEM standards for performance, quality, and ease of installation."
Ram Air Specialists
Brief Description: Our ram-air intake system is designed to optimize the intake design of the C6 Corvette. Test results show 35 percent more airflow than the factory intake system. Chassis-dyno tests indicate 15 rwhp on a stock LS2. In our testing, dragstrip times dropped by a full 0.4 second, and top speed increased by 4-5 mph.
Trademark Features: The system is designed with rotational-molded and injection-molded high-impact polymers, along with all stainless hardware. By using quality workmanship and premium components, our ram-air intake is an OEM-grade product, and yet it's approximately half the cost of some of our competitors' systems.
Quote from Company: "We set out with a simple goal of making as much power as possible for a reasonable price. This results in the customer getting the most horsepower per dollar invested, or, as some say, 'bang for the buck.'"
Brief Description: The state-of-the-art Hurricane forced-air-induction system is the best all-around system available. Designed to bring the cool outside air in, the Hurricane is engineered with custom intake scoops that virtually eliminate the possibility of ingesting water, while providing superior cool airflow.
Trademark Features: Carbon-fiber construction, lifetime filter warranty, up to 35hp increase, near-zero water ingestion, free lifetime cleaner and oil.
Quote from Company: "Dollar for dollar, the safest, most efficient horsepower-producing system available."
Volant Cool Air Intakes
Brief Description: Volant has a true, sealed cold-air intake system that shields out engine heat and takes in cool ambient air from below the fan shroud and behind the fog lamps. The cold airbox holds more air for immediate throttle response and incorporates Volant's five-layer Pro-5 cotton/gauze filter element. The result is cleaner, cooler air that increases the horsepower of your engine. The Volant intake fits standard, Z06, and ZR1 model '08-'09 Corvettes.
Trademark Features: Our intake's polyethylene construction is impervious to moisture, oil, and gasoline. Unlike most of the competitors, Volant's air intake looks like an OEM piece and includes cold-air ducts that let ambient air into the intake, sealing out engine heat.
Quote from Company: "Volant is the original sealed cold-air intake system that eliminates hot air and moisture from contaminating your air-filter element."
Zip Products, Inc.
Brief Description: Zip Products is proud to release the Mamba Air Intake System. It's manufactured right here in the USA, with the exact same process used to create chassis, bodies, and other components for today's Formula 1, Champ Car, Daytona Prototype, and NASCAR teams. Beyond its intimidating great looks, every inch of this system has been designed to squeeze out as much air and create as much power as possible. Its beautiful, sleek design flows a tremendous amount of air into your engine without setting off any "check engine" lights. Even the Mamba's filter has a unique and revolutionary design that allows far more air to flow in a smaller space, as compared with traditional-style filters.
Trademark Features: The Mamba is currently the only air intake made out of 100 percent 2x2 twill carbon-fiber and cured in an autoclave. It generates a 20-plus-rwhp improvement over stock (even more when utilizing the Mamba's Carbon Fiber Fresh Air Scoop).
Quote from Company: "The finest CAI on the market. It took three years to complete this project, but we achieved what we set out to. The intake appears factory until you take a second look, and it functions so well that we had to go back to the dyno on several occasions just to believe the results it was producing."
