Replacing a clogged or damaged vacuum connection helps prevent air leaks that can lead to poor fuel mapping or erratic engine behavior.

Installation is straightforward as it threads directly into the designated port on the cylinder or engine block. We recommend checking your vacuum lines for cracks or wear whenever replacing this fitting to ensure the entire system remains airtight. Using a small amount of thread sealant may be beneficial depending on your specific model's service manual requirements.
