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. EuroCustomsPR can confirm fitment and install the set as part of a service or performance build.

Availability and shipping

Special-order availability is confirmed before payment. APR's public product page currently shows a future estimated ship date; direct-account or distributor availability may differ. EuroCustomsPR will confirm current price and lead time for the complete six-plug set.

Warranty

Manufacturer warranty eligibility and dealer claim routing follow APR's current policy and will be confirmed with the order. Installation, calibration, or vehicle-condition issues are not represented as manufacturer defects.

Frequently asked questions

Is the APR retail price for one plug or a set?

APR part Z1004081 is sold individually. This EuroCustomsPR listing includes six plugs and is priced as six units at APR's current listed unit retail.

Are these intended for a stock 992?

APR describes Z1004081 as a direct-replacement performance plug for stock and tuned supported engines, with a colder heat range for higher-load use. Final selection should match the vehicle and calibration.

Do I need APR coils?

No coil purchase is automatically required. Inspect the existing coils and replace them only when the build plan or component condition supports it.
