OEM Nissan - Nismo Pilot Bushing Needle Bearing for Manual Transmissions - Nissan 240SX 300ZX 350Z 370Z Skyline GT-S GT-R | Infiniti G35 G37 (32202-09500)

The original pilot bushing is just a metal sleeve that the transmission input shaft slides into. These sleeves usually get worn out, and leave shavings inside the bell housing. The Nismo Needle Bearing rotates with the transmission input shaft, and won't cause any wear on either the bearing or shaft.
