Adjustable Throttle Body Spacer

The K-Tuned Adjustable EP3 Pulley Kit addresses common accessory belt tensioning problems found in K-series engines equipped with an auto tensioner. Unlike fixed OEM idler pulleys, this adjustable kit allows users to manually fine-tune the accessory belt length, ensuring it stays within the ideal service window. This adjustability is especially valuable as belts naturally stretch over time, and it proves highly beneficial for K24 and K20 engine builds that often involve mixing components. A key feature is the option to retain the air conditioning system, offering greater flexibility for builds where A/C functionality is desired. The kit is available for all K-series engines featuring an auto tensioner, with specific configurations offered for K20 and K24 engines. The product description notes that the kit does NOT fit the K24Z3 engine.
