GReddy/Trust Airnix Suction Kit (STOCK MAF) For Nissan Skyline R32 R33 R34 GTR 12020971

The factory air intake system on the R32, R33, and R34 Skyline GT-R is one of the biggest restrictions holding back the RB26DETT’s potential. Tight bends, small piping, and the stock airflow meters create turbulence and limit airflow, reducing throttle response and overall power. The GReddy/Trust Airinx Suction Kit for cars with Stock MAF (12020971) is engineered specifically for models retaining the factory airflow meters, replacing the restrictive factory setup with a high-flow, polished intake system that allows your twin turbos to breathe more freely and deliver stronger, more responsive performance.

This complete kit includes polished intake piping, dual high-flow Airinx AY-SB filters, silicone couplers, gaskets, clamps, and all necessary hardware for a clean, professional installation. The modern design creates a powerful ram-air effect that draws in cooler, denser air, resulting in improved engine efficiency, quicker spool, and noticeable gains in horsepower and throttle sharpness. It is the ideal upgrade for owners keeping the stock meters while seeking better intake efficiency and a more aggressive under-hood appearance.

At Terra Firma Automotive, we supply this genuine GReddy/Trust Airinx Suction Kit for cars with Stock MAF as a premium performance upgrade for R32, R33, and R34 GT-R owners. The polished piping and high-flow filters not only enhance performance but also add a striking visual upgrade to the engine bay. Whether you’re building a street machine or a high-power track car, this suction kit transforms the weakest link in the factory intake into a strong, efficient system that helps unlock the full character of the legendary RB26DETT.
