Upgrade to the SCK Racing CNC billet machined engine oil pump for much faster flow rate over stock, and even some other racing ones. If you have a big bore kit installed or other race performance parts installed, it is advisable to replace the internal engine oil pump to a high flow unit to help with cooling and reliability.
Please check and compare your engine oil pump type (V1/V2) with photos first before purchasing, as some year models overlap in some regions.
