This FabSpeed EVOMSIT Tuning System for Porsche 996 Turbo improves engine power and torque for impressive performance gains.

NOTE: This is not a physical/shipped product.  This upgrade requires you to send FABSPEED your ECU for re-programming.  You will be emailed a download link with detailed instructions after adding this to your cart and checking out.

SHIPPING DETAILS: Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser.  The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with.  (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground.  If you ship it via Overnight, we will ship it back via Overnight.)

Fabspeed has developed this intake kit to take advantage of cooler air charge temperatures found low and at the front of the car, increasing the density and oxygen content of the incoming air charge.  It is constructed out of C.N.C. air craft machined with T304 Stainless steel with a BMC air filter, while maintaining the stock mass air flow plastic sensor grate and location for maximum power and no Check Engine Light.  Do not settle for and anything less then perfection in your Porsche 996 Turbo S and get your Fabspeed intake kit.
