aFe MagnumFORCE Stage-2Si CIA System w/ Pro 5R Filter 12-15 Porsche 911 Carrera S (991) 3.8/3.8LDual 360 degree radial flow air filters feature our pre oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. They provide your engine with the largest amount of high flowing air, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street and or track use. Their inverted tops make for more filter surface area, resulting in longer service intervals.

Dual 360-degree radial flow air filters feature our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. They provide your engine with the largest amount of high-flowing air, usually resulting in the highest power gains out of all our filter media options. This media is perfect for street and/or track use. Their inverted tops make for more filter surface area, resulting in longer service intervals. The smooth housing, constructed of cross-linked polyethylene (XLPE), is used to minimize the number of components and ensure the coolest air intake charge available. The housing utilizes the factory OE air inlets. A vacuum-formed removable cover seals the system, ensuring cool air delivery to the engine, but can also be removed for extra air flow if desired. This system features a high quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat soak resistant and extremely durable. The computer designed system utilizes factory mounting locations, minimizing the use of unnecessary hardware and ensuring a perfect fit every time. Its innovative design makes for a hassle-free, direct bolt-on installation process that requires no cutting or drilling. In 2020, Porsche created a recall to add a heat shield in the engine compartment under the air box. The heat shield is to prevent foreign objects left in the engine compartment to make contact with hot exhaust system components and ignite. aFe POWER housing will currently not fit with the heat shield added after the recall. aFe POWER is working on making an update to the housing to allow fitment with this heat shield.

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
