The SWR (Sunworld racing) engine oil pump has up to 40% faster flow rate than the stock. 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. The higher rate of engine oil flow will help cooling and reliability. Even more effective if you install an oil cooler kit.
Please check and compare your engine oil pump with photos first before purchasing, as 2014 year models overlap in some regions.
