Spirit Road Oil Catch Tank for 90-05 Miata


8 in stock



I designed this oil catch tank for all the different ITB (individual throttle body) iterations on my demo car.  Back in 2017, I was looking for a universal and/or off the shelf solution, but there weren’t any.  So I drawn one up and sourced all the materials/bits and had it tig welded together.  I tested it several times and made several revisions.  The final product has an internal baffle, allows use of 8 AN fittings, an air filter and a drain plug.  The oil catch tank also mounts to the chassis utilizing an existing hole where the oem airbox mounts to.  This oil catch tank is a good solution for anyone utilitizing ITB’s.
