Honda K20A2 Knock Sensor - 30530-PRB-A01
Keep your K-series running at peak power and reliability with this genuine Honda K20A2 knock sensor. Engineered by Honda for the 2002-2004 Acura RSX Type-S, the sensor’s piezo-electric core “listens” for detonation and instantly signals the ECU to adjust ignition timing before costly damage can occur. Because it’s an authentic OE component—not an aftermarket imitation—you get perfect plug-and-play fitment, corrosion-resistant housing, and the precise frequency filtering your K20 or K24 build depends on.
Whether you’re refreshing a tired RSX engine, chasing an elusive knock-related DTC, or buttoning up a K-swap in your Civic, Integra, or Del Sol, this Honda-branded unit restores factory accuracy so you can push boost or higher compression with confidence. Simply thread it into the block, click the connector, clear any stored codes, and hit the road or dyno knowing your ECU has flawless knock feedback.
