  1. Fantastic quality and easy install

    Posted by Adrian M on Jul 15th 2020

    My turbocharger was do for a rebuild and I needed to replace the existing oil drain flange i came across this one from boost lab and I really liked the design of it, on how it makes the oil flow out of the turbo for a zero chance of any oil backing up. The gasket that comes with the flange is made of some type of silicone which is a much nicer quality over the regular paper one. I would highly recommend this flange to anyone with a highly modified turbocharged vehicle.

  2. Great product

    Fast shipping great product and affordable!! Great company to deal with

  3. great product need more options for different frame turbos

    Posted by Unknown on Aug 29th 2017

    Boost lab exceeded my expectations , got exactly what was described . If you have a hks , greddy or eBay cxracing style this might not work unless you clock the drain to 45 degrees to clear the runner . I would love to see an updated version for gt42 style turbos that has sort of an S shape to it . This would work better on a cast log style manifold . They're price is much better than competitors on this product and they are lightning fast to responding to emails
