The OEM manufacturers spend a lot of time reducing turbo noise at the expense of horsepower.  By letting the turbo ingest all the cold air it needs, the Alpha Mercedes-Benz AMG M133 Carbon Fiber Performance Intake System boosts power significantly. In addition, it allows you to hear the turbo spool up which is something you as an enthusiast can appreciate.

Simple Upgrade, BIG Power Increase

Our engineering team immediately noticed a considerable level of restriction in the stock intake system and solved the problem by designing a smooth transition to a much larger filter.  By upgrading the size of your 2.6″ factory inlet filter to a robust 4″ design, we drastically reduced the high pressure drop –  a sure indicator that your stock intake filter is choking your M133 2.0L turbocharged engine. By simply installing this air intake upgrade on its own, you’ll be rewarded with a 20+HP increase!

Smooth Design And Unobstructed Airflow

In an effort of cost savings by the manufacturer, your M133 2.0L turbocharged engine comes equipped with a corrugated plastic air duct which disrupts airflow. To make matters worse it also features a big support “pillar” in the middle to keep the flimsy plastic from collapsing which hinders power output. With the Alpha Carbon Fiber Cold Air Intake Duct, we eliminated these restrictions – supplying your engine with all the air it needs!


Cool Air For Your Hungry Turbocharged Engine

Often, aftermarket intake systems feature an open filter element which actually reduces horsepower by drawing hot air from within the engine bay.  This may net you some power on the dyno while the hood is open and cooler air is available, but decreases performance when the hood is shut.  By taking full advantage of cool outside air provided by our sealed air box and inlet design, you reap the benefit of maximum power as you fly through the gears of your Speedshift DCT 7-speed transmission.

The Difference Is in the Details

We took the time to match the carbon fiber weave pattern and finish to match your A45 AMG engine cover. In addition the Alpha logo matches in color to the AMG logo and trim found under the hood giving you a super clean look that will be sure to impress your friends!

 

 
 
Built To Last The Life Of Your Car

CNC’d billet aluminum construction and an anodized coating ensure this piece will look and perform great for years to come.  The smooth and strong mounting surface for the air filter ensures a tight seal.  Couple that with a purpose built, synthetic high-flow dry media filter means you won’t have to buy those cheap factory paper filters down the road.  Simply remove and blow off the filter with compressed air periodically or wash out and let it dry.  No messy oils or special chemicals needed.

 

Easy, Non-Invasive Installation

Alpha Mercedes-Benz A45 AMG Carbon Fiber Performance Intake System requires no cutting or permanent modifications to your car.  It simply bolts into the air box in 15 minutes or less.

  • Replaces factory ducting for cool air charge and maximum power
  • Reduces turbo lag
  • Smooth transition for best airflow
  • No computer tuning needed
  • Installs in 10-15 minutes

Product Notes

  • The filters use specially designed media that allows performance and efficiency to be restored to near new each time by simply using compressed air (30-40 psi) from the inside out, making frequent washing unnecessary in order to restore filter performance. For a deep cleaning from extreme environments, a biodegradable cleaner such as Simple Green or other mild shop degreasers can be used. Simply place the filter in a solution or spray the cleaner on the filter. Allow the solution to loosen the particulate and then rinse thoroughly. Shake the filter or use compressed air from the inside outward to remove residual water and allow a full 24 hours to dry.
  • As these motorsports grade carbon fiber parts are hand laid, slight imperfections or weave pattern variances can be expected.

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.
