Secret Weapon Air Intake System (307-158-101) by Weapon-R®. The Secret Weapon Air Intake System uses patented technology to feed the engine 3 times as much air as other systems. As a result, engine performance is increased more than with any other system available.
- Patented technology increases airflow 3 times more than conventional systems
- Each system is tuned to maximize engine performance output
- Every system includes the revolutionary Secret Weapon Air Filter
- Dyno-tuned air intake pipe constructed of CNC mandrel-bent 6061 aluminum for smooth airflow
- Comes complete with all necessary mounting hardware and comprehensive installation instructions
- All Weapon-R foam air filters are backed by the Weapon-R Million Mile warranty
To create an air intake system with the highest airflow possible, the engineers at Weapon-R experimented with basic laws of physics. They found that by creating two different air velocity profiles in the intake tube, both traveling at different speeds, it increased overall air speed and volume to the engine, naturally feeding the engine 3 times more air than a conventional air intake system. To implement this patented technology, Weapon-R CNC mandrel-bends 6061 aluminum to the desired shape, and then polishes it to a show quality finish. The intake tube is then matched with Weapon-R’s Secret Weapon air filter. The Secret Weapon air filter features a tuned velocity stack to increase velocity and decrease turbulence. The dramatic increase in airflow results in a greater increase in engine performance than would be possible with any other air intake system.
Every Secret Weapon Air Intake System comes with everything necessary for installation including comprehensive instructions.
Weapon-R® Ram Air Kit II turns your air intake system into a Ram Air Intake. The Ram Air Intake brings cooler air to your intake system. Cold air is denser and contains more oxygen and cooler engine air inlet temperatures result in more power. Furthermore, the Ram Air tube is made from a high temperature fire resistant plastic, to resist heat soak which robs horsepower from your engine. The Ram Air Kit is easy to install. Just connect the hose to the top of the air filter, mount the velocity stack in the lower part of the grille and attach the hose.212.50Brand: Weapon-R Part Number: 307-158-101

Got this in a few days after payment. Very easy to install. I know very little about cars, but it was straightforward. It is a little pricey. My car sounds like a V8 as soon as I get 2500 rpms. It does add a little acceleration but not much. It looks great in the car. Overall, this is worth 200$+. The biggest downfall of it is the extender tube they gave me, since it can not fit in around my air intake because it's compact.2 people found this review helpful.Was this review helpful for you?

First of all, the installation instructions are vague. Otherwise, the product works pretty well! No complains so far, only had it on for a couple hundred miles. The Aurora sounds even better now!2 people found this review helpful.Was this review helpful for you?

Don't get me wrong, I love the sound my car makes when I take off, but the only problem I have with the system is that I have a Ram air system and the item didn't fit to it.4 people found this review helpful.Was this review helpful for you?

I put this intake on my van with the ram air kit and it made a huge difference. It sounded nicer, there was more throttle response and it accelerated much quicker. This is a good part and I highly recommend it.Was this review helpful for you?

I ordered this part for my buddy's 96 Buick Regal 3100, and right after we installed it, we noticed a big power increase, fuel economy increase, and it also made the engine sound mean as anything. I am ordering one to put on my 2001 Dodge Grand Caravan 3.8L V6 because the kit looks like it will fit my van perfectly. This is a very good part and I highly recommend it.3 people found this review helpful.Was this review helpful for you?

I was looking for some extra performance in my '03 Grand Am. My exhaust system is completely overhauled so I figured it was about time to change my intake. Gave a monstrous boost of power in the high rpms and added a roar to the high rpm sound. Great product I would recommend it to any performance junkie.5 people found this review helpful.Was this review helpful for you?
