Product Details

The Weapon-R Secret Weapon Intake is a performance short ram air intake system engineered using Weapon-R's patented dual-velocity technology to significantly increase airflow to the engine. By generating two distinct air velocity profiles simultaneously — one traveling faster than the other — the system delivers up to 3 times more air volume than a conventional factory intake setup, resulting in improved throttle response and engine performance.

Key Features:

  • Patented Dual-Velocity Design: Creates two air velocity profiles to maximize airflow volume and speed to the engine (USA Patent #7,263,961B2)
  • CNC-Mandrel Bent 6061 Aluminum Intake Pipe: Precision-formed on an automated CNC mandrel bender for smooth, consistent bends that minimize airflow restriction
  • High-Polish Show-Quality Finish: Mirror-polished aluminum pipe adds underhood visual appeal alongside functional performance gains
  • SW1 Performance Air Filter: Features a tuned velocity stack designed to increase incoming air velocity while reducing turbulence
  • Open-Pore High-Density Foam Filter Media: Reusable and washable construction for long-term serviceability
  • 1 Million Mile Limited Warranty: Weapon-R backs this intake with an industry-leading warranty
  • Broad Application Coverage: Available across 250+ applications for cars, trucks, and SUVs

This intake system does not carry a CARB Executive Order (EO) number and is not legal for sale or use in California. Professional installation is recommended.

good prices

Quick and easy. Could have left or right side in description though. Other than that 1 phone call cleared up the left and right confusion and placed my order. Great service. I even used again for my rear Lateral arms I just purchased

Good so far with a lot details about parts. very good prices

Great experience

Good Price

Was a little hesitant to order from autoplicity at first but after numerous orders now, this and rockauto are my two go to places for parts. Best prices and fast shipping!!!

Best prices, super fast shipping, will buy from again.

it's so easy I am in the for first time using to buy online because I know speak and read good English but it's so easy to buy it thank you have a great day

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

GREAT!!

Amazing! Product was exactly as described, price was excellent, and shipping was extremely fast. Will buy from again!!

Great place to shop online. The best price on the internet and super fast delivery. Shop with Autoplicity, highly recommended.

I was very happy with Autoplicity and my order of the MMRAD-MIA-90X Mishimoto radiator for my Miata. I am in the process of building a Spec-Miata for racing and trying to keep the costs down. I found Autoplicity to have the best prices on the net. I received the rad real quick. There was a problem with the radiator but the guys at Autoplicity were easy to work with and I am expecting the new radiator in a week or so.
