1. TB401A-NS08A

The new Tomei ARMS Mx-Series Turbocharger improves upons Tomei's original M-Series turbocharger design with the inroduction of a new lightweight billet wheel, multi rate billet actuator, and the very same ARMS technology Tomei is known for!

The Tomei ARMS Mx7960 Turbocharger Kit includes turbocharger, and all associated gaskets, lines, and hardware needed for install on your SR20. This turbocharger kit is rated for an approximate 400HP, depending on supporting mods.

The Tomei Mx7960 works well to suit the SR's mid-range characteristics, whilst still being a good performer up towards the higher power band. The Mx8270 however, even being a bolt on application will deliver the punch of a full peak power type turbo kit.

CNC Billet Compressor Wheel

The newly designed Billet Compressor Wheel offers significant improvement over traditional cast compressor wheels. Machined from aerospace grade materials, these highly durable lightweight compressor wheels feature thinner blades with a larger surface care for significantly improved airflow and turbo spool.

Multi Range Billet Actuator

A large capacity multi rate billet actuator is utilized, with a reinforced forged billet construction. Includes a total of 6 springs for fine boost adjustments. Up to 3 springs can be combined to find the perfect setup. Swivel type nipple allows for greater freedom when routing hoses.

A Lungful of Freedom
Size: 9.7" x 9.3" x 1.8"
Dateline: The Passenger-Side Footwell of a Toyota Venza, Sunday Night. We spend our lives in sealed metal boxes, hurtling through a thick, invisible soup of our own collective filth. A foul cocktail of exhaust fumes, road dust, tire particles, and whatever strange, pollen-based miasma the world decides to throw at us on any given day. To breathe that poison in, unfiltered, is an act of slow, unwitting suicide. You need a line of defense. A gatekeeper for your own lungs. Enter the Bosch 6055C HEPA Cabin Air Filter. It is not a glamorous part. It is not a performance upgrade that adds horsepower or prestige. It is a simple, pleated rectangle of paper and charcoal, a humble guardian destined to live out its days in a dark plastic cave behind your glovebox. But its mission is a noble one. The replacement process is a moment of pure, unadulterated, five-minute victory over the dealership's service department. You pop open the glovebox, you unclip the old filter tray, and you pull out the old soldier. And what you find is a horror show. A grey, matted testament to the unseen war it has been fighting on your behalf, choked with leaves, dirt, and the ghosts of a thousand diesel trucks. It is the face of the enemy. You unwrap the new Bosch filter. It feels solid, well-made. The pleats are clean and numerous. I laid it side-by-side with the outgoing Denso filter—a brand that supplies the automakers themselves—and I could find no meaningful difference. The quality was equal. The construction, robust. This was no flimsy, cut-rate pretender. This was a serious piece of hardware from a serious company. You slide the clean, white Bosch into the tray, snap it back into its dark little home, and close the glovebox. The deed is done. You have performed a life-saving transplant on your vehicle's respiratory system in less time than it takes to listen to a single pop song. And the value… the value is the sweet, sweet punchline. For a fraction of what a dealership would charge you for the same simple service, you have installed a top-tier, HEPA-grade filter from one of the most respected names in the business. You have guaranteed yourself a clean, breathable bubble of personal space as you navigate the toxic jungle of the modern roadway. This is not just a filter; it's a small, affordable act of rebellion. It’s a declaration that you, and you alone, are the master of the air you breathe. It is a simple, effective, and profoundly satisfying piece of gear. Highly recommended.

Great Upgrade to your Cabin Filter. Fits 2018 Subaru Outback
Size: 9.7" x 9.3" x 1.8"
This is a great filter upgrade to your cabin filter. This is better than the Subi standard part. Fits my Subaru outback. NOTE: Subi marks their filter with an 'up' arrow; however, this filter is marked with a 'airflow' direction. Direction of air flow is toward the blower motor so it will point downward when you install it.

Air flow direction
Size: 9.7" x 9.3" x 1.8"
Good product. Fits fine. This is not a Toyota part so Air Flow Arrows on filter should face down in a 2015 Toyota Rav4.
