  • Eliminates oil blow-bye  issues associated with performance intakes on M8 engines 
  • Patent-pending oil catch is integrated into the backing plate and stops any excess breather oil from reaching the air filter. Oil catch is serviceable, simply bolt-on and off when your ready to wash/service the air filter
