K&N 90-93 300ZX Turbo/Non-Turbo Performance Intake Kit

K&N Engineering is well-known for making performance air filters and intake systems that help engines breathe better. For your 1990-1993 Nissan 300ZX, this 57 Series FIPK (Fuel Injection Performance Kit) is designed to replace the factory air filter and restrictive air box. By reducing intake restriction, this kit allows your engine to take in more air, which can lead to more usable power and better acceleration across the entire RPM range.

The kit includes a large, round K&N high-flow air filter with a chrome top that fits onto your factory mass air sensor. Air is then channeled directly into the throttle body. This setup is built to last, with the oversized air filter typically needing service only after up to 100,000 miles, depending on your driving conditions. Installation is usually straightforward, taking about 90 minutes with common tools, and the system is street legal in all 50 US states.
