A distinction is made between highflow and bypass, depending on how you install it hydraulically. Remember: a clogged bypass filter will only stop it from filtering, then your oil cooler will be the "filter". A clogged highflow filter will "greatly" reduce the coolant flow. I installed the IPR highflow 2 years ago. In the beginning I cleaned the filterscreen every 3-400mls, now every 4-5000mls. I recently made this video where you can see a "clogged" filterscreen at the beginning.
I did mine before. Works great.
Seems you can't get one that won't leak on the line fittings after a year. I've been through 2.
I put a mishimoto filter on 4-5 years ago, not leaking yet but I didn't use Teflon tape, I used the old plumbers Fibre - can't remember the name - no problems!
Great input on Mishimoto filtertration. Im new to this and obviously bought a low end kit. Never the less I need to answer the 2 questions before installing.

*What advantage or disadvantage doe high flow this have?
* heater heat reduction depending on where hooked up?
I’m not sure what you are calling up/lower hose but it goes on the one that connects to the metal tube by the alternator. Wherever you decide to put it on that line, be sure it’s ahead of the heater valve if your truck has one. If it’s behind the valve towards the firewall it will only see flow when the heater is on.This style of filter is a bypass and High-Flow is just marketing ****.

I do like your idea taking pressure side from the intake? Wouldn't mean constant flow no mater thermostat state?
So from my searches I've found there is the
* inline way / - pros - with high flow the best way / - cons, if plugged then ...
* bypass / - pros - well, it will bypass if plugged / - cons, maybe not as efficient as inline? but definitely not if placed behind a shut off valve...
For those that have a vacuum valve, the flow to the heater core will shut off when the AC is switched to MAX. It's common to splice in the bypass filter before that valve if you have it. Depending on where your filter output goes will determine if the flow continues when the valve is shut off, which is why most people put the filter return into one of the degassing lines heading back to the degas bottle. If it's a 3/4" flow, then it goes into the heater out, return line, which then will diminish the flow through the heater core.
The heater circuit is a bypass in itself. A bypass from the normal engine flows to provide heat. It will operate no matter the thermostat position. So the bypass filters are a bypass to the bypass in technical terms, but in reality flow as best they can no matter.
