Description
xShop Now Genuine Porsche Spark Plug Online – Part 99917010390
This is the genuine Porsche Spark Plug 99917010390. It suits naturally aspirated flat six and V8 engines. It delivers the arc energy these engines need each cycle.
This plug differs from Panamera plug 9A790560150. The turbo Panamera uses a Grade 7 heat range. It also runs a tight 0.7 mm gap. This plug runs Grade 6 with a 0.9 mm gap. It matches the lower charge density of non turbo engines. Do not swap them between models. The wrong heat range can cause knock or fouling.
A weak plug often shows at idle first. A flat six may feel rough at low rpm. The shake fades above 2,000 rpm as speed rises. That rough idle can warn you before a fault light shows.
Replace the full set every 60,000 km. Order six for a flat six or eight for a V8. Buy from EuropeanAutoSpare for fast global delivery and expert support.

Technician’s Advisory: These models feature an Electronic Parking Brake (EPB) on the rear calipers; a diagnostic tool is mandatory to put the system into "Service Mode" before pad replacement to avoid damaging the electric actuators. Always replace the one-time-use electronic wear sensors (one per axle) to reset the dashboard maintenance light. Due to the high weight of the vehicle, ensure high-temp anti-seize is applied to the hub mating surface to prevent rotor seizing, and verify if the vehicle has 19", 20", or 21"+ wheels as rotor diameters vary significantly across trim levels.
FAQs
xFrequently Asked Questions
Yes, this is a genuine Porsche OEM spark plug (Part No. 99917010390). It is specifically engineered to meet the ignition requirements and thermal profiles of Porsche’s naturally aspirated performance engines.
This component features a Grade 6 heat range with a 0.9 mm gap, optimized for the combustion cycles of naturally aspirated engines. In contrast, the Panamera 9A7 plug uses a colder Grade 7 range and a tighter 0.7 mm gap specifically for turbocharged applications; these should not be interchanged.
Quantity depends on your engine type: six plugs are required for flat-six or V6 naturally aspirated variants, while eight plugs are necessary for the Cayenne V8. To maintain balanced ignition and idle stability, we recommend replacing the entire set during service.
This spark plug is a direct fit for the Porsche 911 (996 and 997 Gen 1 generations) as well as the Cayenne V6 and V8 (9PA generation). To ensure compatibility with your specific model year and engine code, please send your VIN to European Auto Spares for professional confirmation.
