Has anyone heard of and/or tried these o-ring seals ? , if so how good are they ?.

 

i have not actually seen what your talking aobut but Fel Pro is top quality ****! is this on their website?

 

Cant say , a friend got the kit ,i'll find out and let you know.

 

Do you know what material they are made out of?
that would be awesome, if a company like Felpro started making our gasket kits.

 

Started? They've been available for years. I never bought one because the Mazda kits are usually cheaper.

Mazda had a lot of trouble developing the special multi-layer inner coolant O-rings, as good as Fel-Pro is I would not trust them for that part

 

it is also very possible that the fel pro kit is a repackaged mazda one. the 12a kits are under $100 retail

I have seen them used with no issues whatsoever.
