Product Details
The Honda OEM Knock Sensor is a genuine factory replacement designed for the 2002-2006 Acura RSX Type-S equipped with the K20A2 and K20Z1 2.0L DOHC i-VTEC engines. This sensor monitors engine vibrations associated with abnormal combustion, commonly known as engine knock or detonation.
When knock is detected, the sensor sends a signal to the ECU, allowing the engine management system to adjust ignition timing and help protect the engine from potentially damaging combustion conditions.
Over time, knock sensors can fail due to heat, vibration, electrical damage, or damaged wiring connections. A malfunctioning sensor may cause a check engine light, reduced engine performance, hesitation, or diagnostic trouble codes such as P0325.
Manufactured to Honda's original equipment specifications, this knock sensor provides accurate detection, dependable operation, and factory-quality fitment. It's an excellent replacement during engine repairs, K-Series rebuilds, and compatible engine swaps.

So like a bunch of others I accidentally broke my knock sensor, while doing my k24 swap. Luckily Clubrsx has my back and got a new one to my door in a couple of days car runs like a dream

Literally half price of any other knock sensor I could find. Its a royal PITA to change, but this worked perfectly, and CRSX got it to me with super fast shipping.

Car was sluggish and misfiring at times and replaced this and car runs like a champ once again.
