*by A***  on Reviewed in the United States on June 2, 2023*

I use these to protect my aftermarket aluminum intake manifolds, aluminum radiators and other aluminum cooling system components.  You usually have to plug an extra port anyways with a plug so why not put this in instead. I have see an Edelbrock intake corrode thru inside near the thermostat and allot water into the crankcase, not good!  Keep that coolant flushed too will keep down this corrosion!!
