Franklin Engineering Limited is proud to manufacture billet aluminium oil filler tubes for Mazda rotary engines.
CNC Machined from high quality 6061 aluminium, these oil filler tubes replace the standard metal filler which sticks up high in the engine bay. They fit straight into the 29mm hole in the centre plate.
Suits standard Mazda oil cap and most aftermarket oil caps, including our own billet rotor shaped caps.
The filler necks have a 1/2" NPT thread in the side for fitting an engine breather. We also have shorter filler necks available with no breather fitting, check out our other listings.
