I installed the Tefba on the zx2 about 70 miles ago. coolant temps are running the same/nearly the same as before the filter. So I don't believe it to be overly restrictive. I have done a drain and refills of coolant every year for the last 8-9 years so I don't believe it has a lot of trash in the cooling system.It is kinda a pita to service. I plan on servicing at my next oil change in about 2,000 miles or when the temp needle starts to creep up.
Any issues here????
