Usually Purolator filter is $6. So $72ish plus $6 = $78. (+$1 for crush washer). I'm at 97,xxx miles (started at 3,600 miles) and 450+ autox runs and few HPDE later, Z pulls like brand new. NO issues with that Redline and purolator puro 1 combo
Some of our vendor carries the Redline fluid. If not, I buy from Summit every now and then.
