Mazda Rotary Short Oil Filler with Breather & Cap Combo021-004, 021-006
FranklinPerformance is proud to manufacture billet aluminium oil filler necks and caps for Mazda rotary engines.
CNC Machined from high quality 6061 aluminium and black anodised for great looks and corrosion resistance, these oil filler tubes and caps replace the standard metal filler and plastic cap which stick up high in the engine bay. The filler necks fits straight into the 29mm hole in the centre plate.
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 and the oil caps available separate, check out our other listings.
