I bought Victor Reinz intake mani. gaskets @ $52 instead of OE BMW @ $90. I don't know how the OE gaskets feel but these feel very stiff and im planning to apply some vacuum grease on them before i install.
I didn't know how expensive this stuff is and i don't want to waste money on the wrong one.
The Dow stuff looks decent and is about 30 bux for a tube but says its only goof up to 200 degrees Fahrenheit. Is that enough?
I thought Castrol would be the way to go since this is made for automotive applications but its $1000 for 4 grams!!!!
Wow what is vacuum grease made of?
Which one do you guys recommend or have experience with?
