Ram TRX Air Induction

The Ram 1500 TRX is one of the most capable high-performance trucks ever built, powered by a supercharged 6.2L HEMI® V8 that demands a huge, steady supply of clean, cool air. North American Assembly manufactures the air intake system for the TRX at our Auburn Hills, Michigan facilities, bringing the same IATF 16949 certified processes and zero-PPM quality record we deliver on every OEM program. From molded components to final assembly and inspection, every system is built in the U.S.A. to meet Stellantis’ demanding performance and durability standards, helping the TRX deliver the power it’s known for, whether it’s on the street or off the beaten path

Dodge Challenger Shaker

Dodge® wanted to bring back the nostalgic Shaker induction from the 1970 Challenger, paying homage to the muscle cars of years past, in a serialized limited run known as the “Buzz” model in 2014. The project challenged NAA: the top half protruded through the hood as a Class A exterior body component, while the lower half had to be a performance air induction system. NAA stepped up where others were reluctant to venture into this cross-functional realm, and developed the 2014 Shaker for the 5.7L.

It was so well executed, and so desired by performance enthusiasts, that it became a vehicle option on the Challenger 5.7L. NAA developed provisions for the 6.4L as well, and both models ran through the retirement of the combustion-engine Challenger in 2023.

As the program progressed, it became the highest-grossing Mopar® product in Mopar’s 86-year history.

This labor-intensive, low-volume production program brought together a multitude of manufacturing disciplines: sheet molding compound (SMC), injection molding, overmolding, insert molding, laser cutting, steel forming, high-temperature outgassing, CNC machining, robotic machining, exterior prime and paint, convection baking, hand sanding, custom material handling, vision systems, DC torque drivers and certified IATF 16949 assembly processes.

The system was manufactured entirely at our two facilities in Auburn Hills, MI, with 100% of components and tooling built in the U.S. Over the life of the program, NAA manufactured more than 50,000 Shaker assemblies with stellar quality, and not a single Shaker assembly was ever returned by Dodge for any reason.

LS2 Supercharger

The LS2 supercharger was featured on performance models under the Chevrolet and Cadillac brands. Beginning in 2006, the production process brought together components from five major manufacturers.

The manufacturing process includes an automated line with leak checks, part-presence checks and continuity checks on all electronic components. Assembly stations feed the line and feature air-assisted gyroscopic tooling and an LED-guided build process.

Ram Airflow

With the newly styled DT Ram 1500 series light-duty truck, Dodge wanted to offer a high-performance cold air intake. Mopar® approached NAA with a concept that was not your typical air induction system: they asked for one that spans the entire engine bay, from the cowl to the grille.

NAA accepted this almost insurmountable challenge and brought to market a first-of-its-kind cold air intake with several proprietary styling enhancements. NAA did extensive development with Mopar on this unconventional system and was responsible for the unique design, manufacturing, validation and procurement to bring it to market.

The kit was so well received as an aftermarket performance kit that it was implemented on the production Ram GT version of the 1500 series truck with the 5.7L. Styling was a priority, and NAA delivered proprietary insert-molded stainless steel trim and cosmetic Santoprene® convolutes, and developed an injection-molded Long Glass Nylon material that allows the system to span the engine bay. All molding is done in-house by North American Mold, a division of NAA. To further enhance styling, NAA added an argent silver hot-stamped “RAM AIRFLOW.” NAA currently produces volumes of 1,200 per month.

Chevrolet PERFORMANCE

C7 Corvette Cold Air Induction

The C7 Corvette induction system was NAA’s first venture with the GM Performance group. NAA supplied an initial concept of a clear window with the Corvette badge molded into the center. The concept later evolved into a captured window with an engraved logo.

Using CFD analysis to optimize airflow and restriction, along with a new filtration media, NAA was able to exceed performance expectations and increase the C7’s horsepower with a simple airbox and filter change, while adding beautiful aesthetics to the engine bay.

Performance and beauty were the main goals of the program. NAA delivered on both by using new molding materials and methods and by bringing new filtration media to the automotive market. These materials and media quickly became standard in NAA’s product development, further pushing the envelope for what can be achieved while exceeding OEM criteria and standards.

NAA guaranteed GM engineers a 10 HP gain up front if allowed to completely redesign the OEM system
The new system exceeded all GM expectations with 17.1 HP
17.1 HP is the highest power gain through a cold air intake in GM history
Custom performance filter and extensive development to meet GM’s strenuous airflow noise requirements
Zero product returns
NAA’s first program shipped directly to dealers
First to use translucent nylon on a window, with proprietary insert molding

Dodge · 2017–2023

Challenger T/A

With the success of the Shaker Challenger, Dodge continued the nostalgia and approached NAA to design and develop the Challenger T/A, paying homage to the 1970 SCCA Trans Am series race cars and the limited-production Challenger T/A and AAR ’Cuda.

NAA developed a performance air induction system with a hood-mounted duct, providing a robust integrated sealing system that kept hot air out of the cold air stream fed by the hood-mounted scoop.

Originally slated as a three-year FCA program, the Challenger T/A system was produced by NAA until the vehicle was retired at the end of 2023.

Mopar

Mopar T/A Hood Venting System & V2

Mopar began offering a collector car package: a retro-styled T/A hood reminiscent of the 1970 Challenger T/A, paying homage to the 1970 SCCA Trans Am series race cars.

NAA was again contracted to design a hood venting system that provides functional cold air intake to the engine. NAA still supplies this system, which is manufactured at its two facilities in Auburn Hills, MI.

When the cold air intake was updated for the Challenger, Charger and 300C, it created a problem for owners who wanted to install a functional Mopar T/A-style hood. NAA took elements of the 2010 hood venting system and adapted them to the new cold air intake, creatively modifying existing tooling for a cost-effective solution that satisfied customer demand.
