DENSO Auto Parts Spark Plug P/N:3173
DENSO Auto Parts 3502 spark plug for the 2016-2021 Honda Civic 4-cylinder 1.5L, the 2017-2021 Civic 4-cylinder 2.0L and other vehicles ignites the air-fuel mixture in the cylinder through an iridium-tipped center electrode.

It is a spark plug for the 2017-2022 Honda CR-V 4-cylinder 1.5L, and the other vehicles it fits include the 2018-2023 Jaguar F-Pace 4-cylinder 2.0L and the 2021-2023 F-Pace 6-cylinder 3.0L. If your car is not named here, look it up in the "Vehicles it fits" section.
