The K&N 57-3035 is a cold air intake kit for the 2001–2004 Chevrolet Corvette with the 5.7L V8. The manufacturer's design contains a custom rotationally-molded tube and a large filter, and the kit is built to replace the factory air filter and intake tube. Buyers choose it over a stock airbox because the manufacturer guarantees a gain in horsepower and torque, and the washable oiled cotton filter can be cleaned instead of replaced. The manufacturer says that filter only requires cleaning every 100,000 miles under normal highway driving conditions, which keeps recurring costs low over the life of the car.
This C5 intake suits owners searching for a 2001-04 Corvette 5.7 cold air intake, a 57-3035 FIPK upgrade, or a washable C5 Z06 intake. Owners on user forums who have asked about Z06 fit say the setup should match the base car, though one discussion notes that the instructions can call for minor trimming of the radiator shroud, which owners describe as optional for better airflow. Confirm the exact application with the manufacturer before ordering. The manufacturer also backs the kit with a No-Hassle Lifetime Limited Warranty.
The manufacturer lists the kit for the 2001-2004 Corvette V8-5.7L. Owners on user forums who installed it on a Z06 report that fitment matches the base car, but confirm the exact application with the manufacturer before ordering.
Owners on user forums say the instructions can call for minor shroud trimming, but that cutting is not required for the install. Trimming is optional and may allow more fresh air to reach the filter.
The manufacturer states the washable filter only needs cleaning every 100,000 miles under normal highway driving conditions. Harsher or dustier driving may call for more frequent cleaning.
The manufacturer's installation sheet describes a typical install of 60 minutes or less with simple hand tools, and owners generally report that the included instructions are clear. Plan for the intake tube fitment, the mass air flow sensor connection, and the air filter position behind the radiator area. Before starting, check the manufacturer's install sheet for your exact vehicle and whether radiator shroud trimming is needed for your setup.
