ROTOMOLD PLASTIC

This cold air intake is manufactured from a high-quality rotomold procedure that produces a superior plastic material with consistent wall thickness, strong corners, and excellent heat resistance. Enjoy a proper motorsport-designed intake system without compromise.

PERFORMANCE
The internal volume of the intake and its complex shapes are the results of application-specific engineering for the Audi B9 platform. Every inch has been performance designed to feed your turbocharger with the most airflow possible.

VELOCITY STACK
The integrated velocity stack smooths the airflow from the large filter into the charge system with excellent laminar properties. This powerful design detail results in a very high inertia flow with reduced drag and power-robbing turbulence at the critical point as air enters the turbocharger.

MULTI-PRESSURE ZONES
This intake features high and low pressure zones to feed the turbocharger and engine demands for any power goal. The majority of fresh air supply is supplied to the filter from the grill. If additional air demands are required, the intake will pull low-pressure air through the filter cover as needed.

AWESOME SOUND
The stock airbox on your Audi A4 or A5 2.0T has been manufactured to silence all engine and turbo sounds at any performance cost. Upgrading your air system with an IE polymer intake will release a symphony of engine throttle, spool, and blow-off sounds that will be music to your ears.

PERFORMANCE RESULTS
Countless design revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification has resulted in a performance intake design with power gains of up to 10-20HP on tuned engines!

FLOW RESULTS
Back-to-back flow bench testing details consistent airflow gains of up to +70 CFM over stock! This increase shows efficiency over the factory parts and capability to provide increased airflow demands from ECU tunes and performance hardware upgrades.

EASY INSTALL
Install your new air intake with basic hand tools in only minutes. Our polymer intake is a direct factory upgrade with stock-style mounts for a perfect, hassle-free installation.

Truly a miracle worker!!
Size: 100 Count (Pack of 1)
I used to wake up every day and struggle to go to the bathroom. After taking these for just one week straight, I have already started to become normal having at least one bowel movement a day. This is my third bottle. I take them everyday and don't think I will stop.

Only one capsule per day
Size: 100 Count (Pack of 1)
You need to be careful when comparing vitamins and supplements anywhere you choose to buy them because although they will advertise 500mg,for instance, some you need to take two tablet to get that 500mg. I think that is a little shady and makes it harder to compare. I chose to go with the 1 capsule equals one dose brands. It just makes me trust them more. This is one of those brands. I actually have only been taking them for a week or two but if they were not 500mg and a good quality magnesium my body would tell me in just a few days. These have been working fine for my sleep and nerve pain so i do recommend them. There is only one con I would have yo say that I wish they would specify what percentage of which type of magnesium this is. Most likely the oxide at this price but it just would be nice to know. I have the subscribe and save so plan on sticking with it. Good price and it is what they tell me it us plus only one per day. Nice find.

These magnesium capsules are easy to take and seem to be very good quality. The capsules are a good size and easy to swallow. I like that this is a trusted brand, and it fits well into my daily routine. Very happy with this purchase. We have taken several brands and thi brand is the best. We are going to be using life extension for more supplement needs.

helps me sleep
Size: 100 Count (Pack of 1)
i've had bouts of insomia my whole life. i've done melatonin, tryptophan, valerian roots, marijuana (legal in my state), chamomile tea, etc. you name it. i didn't buy this as a sleep supplement, but i notice that it will knock me out in about 30 minutes flat if i take it at night. most of my supplements i take in the morning, but i save this one for night time. an unexpected surprise, quality seems good, nothing but positive words to say about it. the sleep benefits alone make it worth the purchase.
