Simple and Easy

Switched from stock bov to Tial. It’s all the same just a different flange. Great quality and customer service as always.



Ask a Question
  • Will this work with the AMS intake manifold?

    The stock manifold fitment will not, you would need the "Process West" variant.

  • Is that a bung for IAT sensor?

    Yes, we include a bung and a plug for an intake air temp sensor.

  • Which bov does the turbosmart flange fit?

    If its a stock replacement turbosmart you want the stock flange. 

    If its a raceport you want the turbosmart flange.

  • The tial flange is for a 50mm?

    It is a Q/QR flange which is 50mm yes.

  • Would this work with a processwest intake ?

    To work with the PW intake manifold this pipe would require modification. The PW intake manifold moves the throttle body location slightly back.

  • i have ets fmic intercooler , i want to buy this bov pipe can i get the tial flanges with speed density ?

    The SD bung is included with a plug on all these BOV pipes.

  • What’s the best product to clean the piping with for FMIC need that clean what will make it look good again ?

    Wrinkle Black piping is going to be cleaned best with a mild soapy cleaner and water. Avoid heavy degreasers, as they may damage the powdercoat finish on the piping. 

    Titanium piping is cleaned best using something like WD-40 and a microfiber cloth, spray the solvent on and wipe clean using a dry cloth.

  • Which variant would I need if I have a 2.5i big plenum long runner ?

    We don't offer piping to suit the N/A Subaru intake manifold, you will likely need to modify the parts to get everything to line up properly.
