Product Details

The ACDelco 213-3521 GM Original Equipment Ignition Knock Sensor (also called a knock sensor or detonation sensor) monitors the engine for pinging or spark knock. It is a GM-recommended replacement for the original component.

The sensor produces a voltage signal from the vibrations caused by erratic air/fuel mixture combustion. The engine control module uses that signal to adjust ignition timing and the air/fuel mixture. This helps protect the engine from the damage that uncorrected knock can cause.

Key Features:

  • GM Original Equipment ignition knock (detonation) sensor
  • One round connector with one pin terminal

Replace a failed knock sensor to help restore proper ignition timing control and engine performance.

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

I hate surveys

My first experience with Autoplicity has been great. One of the best prices I found for the item. Too, the company is not secretative about itself such as another parts discounter.<br><br>Autoplicity is now "bookmarked" for future purchases!

Great price! Quick shipping. The intake I ordered was $20.00 cheaper than anywhere else I looked. Item was instock and shipped quick. Will order from Autoplicity again!

Great Seller. Fast Shipping and great prices!

Great price and great service highly recommended. Will purchase again

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Great prices, quick processing, and an overall excellent company
