Refer to your vehicle’s Owner’s Manual for more information. **Q: How can I tell if my distributor cap and rotor need replacing?** A: Distributor caps and rotors typically need replacement when you notice engine misfires, difficult vehicle startup, reduced engine performance, corrosion or carbon tracking on the cap, or cracks or wear on the rotor. **Q: What is the difference between glow plugs and spark plugs?** A: Glow plugs are used in diesel engines to preheat the combustion chamber for a cold start. Spark plugs are used in gasoline engines to ignite the air and fuel mixture. **Q: Does the "Service Engine Soon" light tell me when my vehicle needs a tune-up?** A: No. The "Service Engine Soon" light comes on when the vehicle’s computer detects a minor malfunction, an engine emissions issue or that routine maintenance is needed. For more information, refer to your vehicle owner's manual. ## Customer Reviews ### ⭐⭐⭐⭐⭐ OEM part thumbs up *by A***R on February 28, 2026* Fit works perfectly ### ⭐⭐⭐⭐⭐ fits perfect *by K***E on April 24, 2025* great product ### ⭐⭐⭐⭐⭐ Good product 👍🏼 *by J***Z on December 31, 2019* Fast delivery, Packaging and product arrived in good shape 👍🏼 Fit perfect on my 93 Chevy C1500 with a 350. Two screws to take off and place new one right on. Vehicle started right up with no issues. Also replaced rotor, plug wires and pvc valve. All AC delco. Just make sure if you take a spark plug wire off you put it one by one on the new cap. I also used tape and a number on each one. Anybody can do this.
