Berk Technology BT1407-Gasket Motor Collector Gaskets 08+ Infiniti G37 VQ3xHR
Stop using RTV silicone to seal your flanges! Berk Technology is currently the only manufacturer in the world that makes these custom collector gaskets for the 07+ 350Z/370Z/G35/G37. Instead of using a bandaid approach to gasket sealing like our competition, Berk Technology make their own custom gaskets for this application. High temperature softcrush graphite gaskets seal even slightly warped flanges. These are sold in Pairs.
You do NOT need to purchase these separately when using BERK HFC's or test pipes. They are already included!
Note: Our gaskets align perfectly with the OEM flange & our BERK flanges. Our R&D Dept has found that some manufactuerers do NOT machine their flanges correctly and will partially block the exhaust path.
