The quest for more power, louder noises, and a sweet look under the hood is a never-ending battle. While Chevrolet's '99-'03 Silverado provides ample punch and a subtle growl when jamming the loud pedal, more power is always well received. Whether you're towing a trailer, blasting the 1320, or just passing slower traffic on the highway, we could all use some extra ponies.

For years, K&N has been showing us filters that offer our trucks extra protection, and because they're washable, it could be the last filter you have to buy, which saves money in the long run. With that said, the real appeal of K&N products has been the performance gain. Whether you are accustomed to getting 5 to 35 horsepower, freeing up your truck's intake has always meant better performance.

According to K&N engineers, the company's intake kits really don't create horsepower as much as they free it up. By improving the flow of the intake path, offering a larger orifice for the air to travel through, and by using a more efficient, less restrictive air filter, the engine simply gets more air.

While we're sure you've seen previous stories in the pages of Sport Truck on K&N's FIPK (Fuel Injection Performance Kit), the Series-77 is a little different. Unlike the FIPKs, which are made out of roto-molded polyethylene, the Series-77 is constructed out of mandrel-bent aluminum, which is either polished to a high shine or powdercoated gunmetal gray. You will get all of the same performance from the 77 as you would from a traditional intake kit, but you will also get some flash when you open the hood.

Start to finish, the installation took about an hour, including a slight refuel at the local Burger King, and required a flat-tip screwdriver, a ratchet, a 10mm socket, and a 4mm Allen wrench. A little dyno-testing at the K&N facility in Riverside, California, showed 8 more horsepower at the wheels, which is not too bad for a little bit of wrench time and 260 bucks.
