Description
Genuine Spark Plug for the 2011–2018 Porsche Cayenne
This is a brand-new, genuine Porsche spark plug with OEM part number 958-170-221-90. It is the same part installed at the factory on the Porsche Cayenne, so it matches the original fit, finish and performance — no trimming, adapters or guesswork. Mason’s Auto Store sells it below the manufacturer’s suggested retail price, ships it across the USA and checks every order against your vehicle before it leaves our Akron, Ohio counter.
