adding an additional cooler to a tt or one on a NA to begin with. The factory one is sufficient. Man read the posts before challenging this OK. Jim Wolf knows more about these cars than you and if you read the first post you would see this is spelled out very carefully for you. Oh and go look at your posts on mine at Z32.org. Dude get some facts before attacking me OK?? No hard feeling man but you really need to research things a little before stating them as facts. Your ticket site is old news and is a scam. And a aftermarket oil cooler is not needed on NA or TT unless it is high HP modded or racing. Factory is plenty. Also Z's are expensive to modify and read that post at z32.org also and come back with facts next time.
