Product Details

The Weapon-R Secret Weapon Intake is an innovative cold air intake system engineered to maximize airflow to your engine. Unlike conventional single-path intakes, the Secret Weapon utilizes a dual-velocity air chamber design that creates two distinct airflow profiles—one traveling at higher speeds than the other. This patented technology dramatically increases both air volume and velocity, feeding the engine up to three times more air than factory intake systems for improved throttle response and horsepower gains.

Premium Construction:

  • Intake tube precision-bent from high-grade 6061 aluminum using automated CNC mandrel bending equipment
  • Polished to a show-quality mirror finish for underhood appearance
  • SW1 high-flow air filter with integrated tuned velocity stack to optimize airflow and minimize turbulence
  • Open-pore, high-density reusable foam filter element—washable and reusable for life

Coverage and Warranty:

  • Available for over 250 vehicle applications including cars, trucks, and SUVs
  • Backed by Weapon-R's 1 Million Mile Limited Warranty
  • Available in polished aluminum finish only

The Secret Weapon Intake delivers measurable performance improvements while maintaining a premium appearance under the hood. The reusable filter design eliminates the ongoing cost of replacement filters, making this a cost-effective performance upgrade for the life of your vehicle.

First time like it so far

Autoplicity has done everything right. no problems here. would buy from again.

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

A+ Experience. Made a mistake and almost canceled my order thinking that I've found better price. They were very nice to proceed with cancellation, but when I figured out my mistake, they did reverse cancellation without any problems. Prompt and polite response every time. I will use them again for sure.

Simply amazing prices, fast shipping, and easy to work with customer service! You can't find a better place to buy from!

Quick

Very cheap place to get name brand parts! Fast shipping!

Ordered a exhaust and a pressure sensor for my 6.0 diesel. Excellent customer service. Fast shipping, cheapest price on the internet. I will buy from autoplicity again. Thanks!<br><br>Joe
