Magnum Force Stage 2 Aluminum Black Cold Air Intake System with Pro 5R Filter (54-11972-1B) by aFe. The aFe Stage 2 Cold Air Intake System replaces your entire factory air intake system with a large high-flow aFe air filter, open element airbox/heat shield and a smoothly contoured, less restrictive intake tube. This system enables your engine to take in huge quantities of dense, cool, oxygen laden air. The result is better combustion, increased horsepower and torque, and a noticeable gain in performance.

The Stage 2 Cold Air Intake System will give you the greatest possible performance gain and the most bang for the buck. It replaces your factory, restrictive air intake system with the massive aFe performance air filter of your choice, a one-piece open element airbox/heat shield that seals against the hood, isolating the filter from engine heat, and a rotomolded plastic intake tube with smooth bends for increased airflow volume. The increased flow of cooler air to your engine will result in noticeable gains in power and performance. Cooler, denser air contains more oxygen, and more oxygen in your engine's air intake charge means better combustion, resulting in greater engine output.

The aFe Pro 5R air filter was designed to provide the maximum airflow possible, to enable your engine to make the most horsepower and torque. But aFe didn't achieve this by ignoring engine protection. The Pro 5R outperforms most other cotton gauze air filters with a 98.6% efficiency rating. The increased airflow and high filtration capability are the result of the Pro 5R's construction. It's made of 5 layers of progressively finer medical-grade cotton gauze.

The Pro GUARD 7 air filter delivers increased airflow while providing the highest level of filtration efficiency available 99.7%. The patented 7-layer progressive cotton/synthetic media in the Pro GUARD 7 consists of 5 layers of progressively finer medical grade cotton gauze, combined with 2 layers of non-woven synthetic polyester fabric with random porosity.

Competitors use constant size mesh gauze in their filters, which creates voids/openings that can allow dirt to pass through. As the progressively finer layers of gauze are stacked in the Pro 5R and Pro GUARD 7, the randomness of the openings increase, minimizing spaces with no filter media. Dust accumulates on multiple layers, increasing overall dust holding capacity and filtration efficiency.

The Pro DRY S filter combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 3 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.

The pleats in all 3 filters are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structures are made from 100% polyurethane, to withstand extreme engine temperatures.

Powder-Coated One-Piece Heat Shield blocks performance-robbing engine heat. This heat shield requires no assembly and uses factory mounting locations for fast and easy installation.

A specially developed 3-angle velocity stack smoothes the airflow transition from the air filter to the rotomolded intake tube. The precision design and smooth contours of the intake tube maximize airflow volume and speed for optimum power gains.

The aFe Stage 2 Air Intake System comes complete with everything necessary for installation, including comprehensive instructions. It's backed by aFe's limited 2-year warranty and made in the USA.

True To Size
These shorts fit true to size and are so comfortable. They have a drawstring waist, so you can adjust them for the best fit and wide legs. They are 55% linen and 45% cotton so they keep you feeling cool. The classic colors go with nearly any other colors or designs, making them stretch your wardrobe potential and saving you money. They were extremely wrinkled upon arrival, so I used my fabric steamer, and within 5 min they looked perfect. I love these shorts and wear them all the time!

Cute 2-pack pair of shorts
Color: Black, White, Size: Medium, Color: Black, White, Size: Medium
Cute shorts that have pockets and fit true to size. I love that they come in a pack of two as well. The black ones are my favorite and I feel like the fabric is a little softer on the black pair. The white ones are a little thinner than I would like. I was wearing an olive green colored underwear underneath them in the pictures in my review and though you can’t see them much, I do feel like they were slightly visible. The white pair also had a lot of loose strings on them which made me think the quality might not be as good as with the black pair. They washed easily and I hung them up to dry them because they smelled kind of funny when they arrived.

Good value for 2 shorts
These come vacuum sealed and have crazy wrinkles... so be prepared to do some ironing. I ordered the Mediums as I am a 6-8. The black pair feels a bit smaller than the beige pair... with both feeling tighter than I like for comfort. The look nice on, but feel like it constricts my belly a bit too much. Overall a nice basic set of shorts, perhaps size up for a more comfortable fit.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.

Well made, light fabric. Waist doesn't roll.
These bamboo underwear really do keep you cool. They fit true to size, and wear easily. the wide elastic waist band doesn't roll on me. They are comfortable to wear, washed and dried easily. The material has some stretch to it, but not a lot. Well made, no stray strings. Perfect fit for me. Just what I was looking for.
