About this part

This is a conventional resistor plug with nickel center and ground electrodes. Denso's patented U-Groove in the ground electrode leaves room for a larger flame kernel, which the brand says helps cold starts, throttle response and idle quality. The gap is 0.060 inch. Nickel plugs cost less than platinum or iridium but wear faster, so plan on shorter change intervals. Sold individually at $1.56, so order one per cylinder.

Fitment notes

The table lists Denso 5023 for the 1997, 2000 and 2001 Chevrolet Malibu. The rows do not name an engine, so check whether your Malibu has the four-cylinder or V6 and confirm the plug in the table. Missing years may simply not be in the data. Send us your VIN if you are unsure.

Installation notes

Work on a cold engine. Check the gap before you install each plug. Start the threads by hand to avoid cross-threading, then torque to spec. Look at the plug wires or boots for cracks while they are off.
