Chevy And GMC Truck Spark Knock Sensor, 1983-1999

• High Quality Replacement Spark Knock Sensor
• For V8 Engines
• Works For 1/2 Ton And 3/4 Ton Applications

When your spark knock sensor fails, your Truck just can't perform like it should. The knock sensor allows the engine to run with the ignition timing as far advanced as possible. The computer will continue to advance the timing until the knock sensor detects pinging. At that point the computer retards the ignition timing just enough for the pinging to stop. A functioning knock sensor assures that you're getting as much power and fuel economy as is possible from your engine. Don't wait until additional problems occur. Replace that failed sensor in your 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998 or 1999 Chevy or GMC Truck before it's too late.
