ISR Performance OE Replacement Throttle Body Gasket - RWD SR20DET S13

This ISR Performance OE replacement throttle body gasket sits between the throttle body and the intake collector on the S13 RWD SR20DET. Pulling the throttle body to clean it, swap a throttle position sensor or fit a different intake is common work on a 240SX, and every time it comes off, this gasket should go on fresh.

Why a throttle body gasket matters

A compromised gasket at the throttle body lets air past the throttle plate, which the ECU cannot account for. The result is a high or erratic idle, lean readings at low load and a car that feels inconsistent off idle. It is a cheap item that is often overlooked when chasing a vacuum leak.

Install tip

Make sure both surfaces are free of old gasket material and oil residue, then snug the bolts evenly. Do not use sealant on this joint unless the factory service manual calls for it.
