 K&N Engineering developed a 57-Series Fuel Injection Performance Kit (57-3048) that will add 19 + horsepower. K&N's dynamometer chart shows a 19.25 horsepower gain at 5133 RPM on the 2004 Chevrolet Trailblazer 5.3L.

"We had to design a tube that fit within a mid-size vehicle with a big engine," said K&N Performance Kit Manager Bert Heck. "We managed to take the intake tube, keep the correct size along with power."

By replacing your factory air intake assembly with K&N's 57-Series FIPK, your engine will get more air with less restriction. More air means more usable power and acceleration throughout the engines RPM range. Most of K&N's intake kits are relatively easy to install using common tools.

The FIPK uses K&N's high-flow, washable and reusable air filter (RF-1032) which performs up to 100,000 miles before service is required (depending on driving conditions). FIPK's also come with the famous Million Mile Limited Warranty.
