This part is legal under the provisions of EPA’s Tampering Policy dated November 23rd, 2020.

See Emissions Details
The APR Turbo Inlet Pipe is an easy-to-install bolt-on upgrade that eliminates a restriction before the turbocharger. Unlike fabricated units on the market today, ours is cast from aluminum, allowing for an organically shaped inlet that transitions gradually over a large distance. Such a design promotes better flow rather than abruptly reducing at the turbocharger's inlet like other units. It's larger than stock throughout, removes a large internal restriction at the PCV inlet, and outflows the factory unit allowing the turbocharger to operate more efficiently. We fully assemble each unit with a billet securing arm, billet PCV bung and new o-ring. The inlet and outlet are CNC-machined to control tolerances and ensure snug and secure connections. This upgrade is recommended at all stages utilizing an IHI IS12, IS20 or IS38 turbocharger!

  • Question

    Will this part fail emission testing?

    By Andrew Kozozenski on May 5, 2023

    We do not have CARB approval on this part yet, but there's nothing about it that would cause emissions to fail.
  • Question

    Hi, Would this part make me fail emissions testing, I see it is illegal for road use but am curious if it would fail emissions testing. (This is for a track vehicle, but I do not want to cause excess emissions if I don't have to)

    By Ben Goldstein on March 24, 2023

    This will not alter emissions.
  • Question

    Will this void warranties?

    By Adam Messa on June 20, 2023

    It seems unlikely, but anything is possible.
