By replacing your factory air intake assembly with K&N's 57-Series FIPK (57-6013), your engine will get more air with less restriction. More air means more usable power and acceleration throughout the engines RPM range. Dynamometer tests at K&N Engineering's lab show a 10.67 horsepower gain at 5500 RPM for the 2003 Nissan 350Z 3.5L.
"We made 10 plus horsepower by relocating the mass air sensor and staying within the vehicle parameters," said K&N Performance Kit Manger Bert Heck. "K&N replaced the restrictive intake track and airbox with our rotationally molded polyethylene intake."
Installation is purely bolt-on and uses factory holes: No drilling is required and the average time to replace the stock airbox and intake track with an FIPK is about 90 minutes. The kit comes compete with all mounting hardware, silicon hose adapters and stainless-steel clamps.
K&N's 57-Series FIPK (57-6013) uses K&N's high-flow, washable and reusable air filter (RF-1037) which performs up to 100,000 miles before service is required (depending on driving conditions). FIPK air intakes also come with the famous K&N Million Mile Limited Warranty.
