Breathe easier in your Porsche! This A-Premium 2-pack contains high-quality replacement cabin air filters designed specifically for various Porsche Panamera (2017-2023) and Taycan (2020-2023) models with specific engines (2.9L, 3.0L, 4.0L V6/V8). It directly replaces OEM part number 971819429 (and others like PC99343C). These filters are crucial – they clean the air coming into your car's cabin, trapping up to 99.97% of dust, pollen, soot, mold spores, and other allergens. This set includes activated carbon, which also helps reduce unpleasant odors from outside. Each filter measures approximately 9.53/12.4\ L x 5.71/8.74\ W x 1.14/1.18\ H (the set includes two slightly different sizes for the left and right side slots, typically located behind the glove box). They're not washable or reusable, but for the price of a 2-pack, it's an affordable way to maintain your car's air quality. Experts recommend changing your cabin filter every 12 months or 12,000 miles for optimal performance and clean, fresh air on every drive.
