Additional Details

Motul Oil, Coolant and Oil Filter

  Part of the APR Turbocharger System install process requires removal of the OEM Turbocharger. During this process, oil and coolant must be drained and should be replaced to offer superior performance and protection. The APR Turbocharger Systems are now complete turn key solutions, including everything you need down to the oil, coolant and oil filter. During checkout you'll be given the option between Motul Specific 502.00, 505.00 & 505.01 5W40 or Motul Power 300V engine oil as well as Motul Inugel Optimal Ultra Coolant and an OEM oil filter. The Premium Motul lubricant package is included at a much lower than retail price point.
