What is included
Six APR Z1004081 Iridium Pro spark plugs. APR sells Z1004081 individually; EuroCustomsPR configures this listing as the six-plug set required for a Porsche flat-six service.
Supporting components
Inspect ignition coils before installation. APR MS100252 coils can be purchased separately when a complete ignition refresh is appropriate. Plug selection, heat range, and service interval should match the vehicle hardware, fuel, calibration, and operating use.
Installation notes
Professional installation is recommended. Verify part number, thread dimensions, supplied gap, and the current engine-specific torque procedure before installation. Incorrect reach, gap, or torque can damage the engine.
