Fast Eddy Co.'s Intake Test Plates are a great way to make sure you don't have any intake leak issues, and they also help you diagnose other problems that might be robbing you of performance.

Easy to use- just bolt the test plate to your intake manifold, collapse the intake pushrods, and use a mighty-vac style hand pump to see if the system holds vacuum.

If the system doesn't hold 10 inHG for 10 seconds or longer you have a leak that you need to deal with. You can then switch over to positive air pressure to easily find the leak. Detailed instructions included.
